One of the biggest frustrations of having a backyard garden pond is not knowing what to do when the water becomes mucky, green and gross!
Don’t worry, you can clear the water without using harmful chemicals. Keeping pond water clear the natural way is easy, and you’ll be able to enjoy your pond again in no time.
Help! What’s Growing In My Small Garden Pond?
Last summer my little garden pond was overcome with a mossy, weedy growth. The pond water looked green, cloudy and disgusting.
After doing some research about garden pond algae, I discovered that the green stuff growing in my pond was string algae. Yuck!
Turns out that string algae growth in garden ponds is a common problem.
Why You Want To Get Rid Of Pond Algae ASAP
Not only does it look terrible, algae buildup in a garden pond is bad because it can take over a small pond quickly, and eventually starve the fish and plants of oxygen and nutrients.
I sure was nervous when I first started reading about algae growth in small garden ponds.
I was worried that I would have to use a chemical for clearing my pond water, and that the chemicals might kill my fish and plants… and even worse, I would have to start over from scratch with my pond.
Needless to say I was thrilled when I discovered that there is a natural solution to keeping pond water clear and getting rid of algae in garden ponds.
Barley Straw Clears Garden Pond Algae
How To Clear Pond Water Naturally
It sounds strange, but the answer to keeping pond water clear the natural way is barley straw.
Not only is barley straw a natural solution for clearing out garden pond water, it won’t harm your fish or plants – and it’s cheap to buy.
In fact, I’ve read that barley straw works better to clear pond water than expensive chemicals do. Win, win, win, win!
You can find technical explanations for why barley straw works to clear pond water on the internet.
But basically, as the barley straw decomposes it releases something similar to hydrogen peroxide (H2O2) which will eventually choke out the algae.
Whatever the technical reason is, it works great!
Barley Straw For Garden Pond Algae Removal
Natural Pond Algae Treatment Use Tips
You can buy barley straw at your local garden center or on the internet. You can also buy barley straw in liquid form, or you can get barley straw pellets.
When I bought my barley straw, it came packed in small bales that were much too large for my pond (pictured above).
The package says that each bale of barley straw will treat 1000 gallons of water.
My small garden pond holds only 90 gallons of water. So I made a smaller bundles out of the mesh packaging the barley straw bales came in when I bought them.
I used twine string to tie the opening in the mesh closed.
Making Barley Straw Bundle For Pond
It’s best to put your barley straw bundle in the pond near a fountain or waterfall where the water will flow through it.
Once the barley straw starts to decompose, the bundle will sink so it’s no longer visible on top of the water.
It takes a few weeks for the barley straw to begin to decompose and start clearing the pond water, so it will take a little longer to get results using barley straw than it would with chemicals.
If you want to start seeing results faster, there are a few steps you can take now.
Barley Straw Bundle At Bottom Of Garden Pond Waterfall
Easy Steps To Clear Pond Water Faster
- Manually remove algae in garden pond: Start by removing as much of the algae growing in your pond as you can manually.
An inexpensive toilet brush works great for grabbing the string algae and scrubbing the sides of the pond.
Ideally, you would buy a new toilet brush to use specifically for your pond; what would be more disgusting – using an old used toilet brush in your pond, or using your pond brush in your toilet!?
Toilet Brush Works To Remove Algae In Garden Ponds
- Rinse garden pond filter daily: If you have a filter in your garden pond, rinsing it daily during this time will also help to remove the algae faster.
If your pump didn’t come with a filter, I highly recommend you get a universal pond pump filter box. It will make keeping your pond water clear so much easier!
Or you can make your own DIY pond pump filter box using these super simple step-by-step instructions.
Rinse The Garden Pond Pump Filter
- Use hydrogen peroxide to help clear pond water: To help remove the garden pond algae faster, you could add hydrogen peroxide (H2O2) to your pond water.
I don’t know if there’s a special formula of H2O2 per gallon of water, so I recommend doing some research for your specific pond size.
My small garden pond is 90 gallons, and I added a 1/2 cup of H2O2 to the water. Pour the H2O2 over the running water of a fountain or waterfall to disperse it.
Pond Water Is Naturally Clear
Shortly after adding the H2O2 and barley straw to my pond and following these steps to clear my pond water, I started to see results.
In no time, my pond water was crystal clear, and it stayed that way all summer.
How To Keep Pond Water Clear Naturally
Now I put a new barley straw bundle in both of my little garden ponds in the spring as part of my regular garden pond maintenance schedule.
Since doing this, I’ve been able to avoid algae growth in my ponds, and keep the water clear. One small barley straw bundle lasts all summer.
Another thing I make sure to do is remove the leaves and other debris from my pond on a regular basis. My pond skimmer net makes this task super easy!

If you’re having problems keeping your pond water clean and clear, and algae growth is not the issue (or if you’re not sure what the problem is), then I recommend testing the water.
You can get inexpensive pond test strips that are specifically made for testing pond water, and that will help you figure out exactly what your pond water needs.
I love my garden ponds again now that the water stays clear. It’s nice to be able to watch my fish swimming around and feeding on worms and other bugs that fall into the pond.
Plus my garden ponds are constantly filled with frogs and salamanders – a wonderful sign of a healthy, chemical free garden.

Do you have a garden pond? Tell me about it in the comments below.
I wonder if this will work in my fountain? I think I might try it. My fountain holds about 10 gallons of water….and it gets just gross after a while. thanks for the tips! I am a new follower!!! been stalking you on the facebook for a while…but now am on GFC too!
Hi Tootsie! Thanks for becoming a new follower. I enjoy your blog too! Funny you should ask about the fountain. We have moss growth on our fountain too and I just poured some H2O2 in there to see if it would work. I don't see why it wouldn't. What the heck, it won't hurt to give it a try! Hydrogen peroxide is cheap to buy.
Good luck!
Amy
Hello, im curious om the peroxide… my pond is about 390 gal round galvanized stock tank …. how much would i pour in the thanl??? i have about 7 baby gold fish and 5 lg fish . koi. gold fancy tail gold fish ….would it hurt them…. i have one plant in there its a lilly pad lots of green floating algae on the top,i have to skimp off the alea everyday just so i can see my fish….
thanks again..
Humm… I’m not an expert on how much peroxide you should add per gallon of water. I use a 1/2 cup in my 90 gallon pond to help get a head start on killing the algae cause barley straw takes a few weeks to start working. So, you can do the math based on what I’ve used. Make sure to disperse it as evenly as you can throughout the water – don’t just pour it all in one spot. I too have goldfish and plants in my pond, and have never lost any of them because I used peroxide. (I wouldn’t recommend pouring it directly on the fish though.)
I never tried peroxide but did add small amt of Chlorox bleach to a 10 ft pond. Killed the goldfish, Killed the mosquito fish. Never again.
I never had a floating device for the barley I tried. Put it into a nylon stocking and never such much improvement. Am ready to find a float and try again.
Any recycle ideas for the float?
Yes, I definitely would NOT recommend using bleach. That will kill the fish for sure, and might also kill the plants in the pond. Sorry for your loss. 🙁 I’m not sure what you’re asking about a “float”, sorry. I tie my barley straw bundle to the fountain in my front pond, and right at the bottom of my waterfall in my backyard garden pond. The barley straw bundle needs to be next to the running water source in order for it to work. The bundle will float on it’s own, and once it starts to break down, it will eventually sink. I can get it out easily buy just pulling it out by the string so it won’t sink to the bottom. The larger the pond, the more barley straw you need (it has instructions on the package).
Cool! What a great lesson! If I ever get around to building a pond, I'll try to remember this. I love ponds. It will be fun to see more posts about yours!
Hi PlantPostings – Glad you enjoyed the post. Having a pond is pretty easy once you understand the basics of keeping a healthy balance so it won't become a maintenance nightmare. I have a few more posts planned for this summer about my ponds, so stay tuned! 🙂
Amy
Hi There,
I just ran into this problem with my fish pond. I noticed that homedepot sells Barley Pond Clarifier, do u think I can use this for our pond? If so, I have goldfish in the pond now. Should I put this chemical in the pond while the fishes are in there? Would it harm the fish? Please advice. Thanks.
The label should say if it’s safe for use in a pond and if it’s safe for fish. If it’s the Barley Straw extract, then it should be natural and safe to use – but make sure to read the label.
Thanks for the information! When we have a pond(hopefully soon), it'll be good to know about these things! I never even thought about the problems with a pond!
Hi RandomGardener – Funny! I never thought about problems with a pond before I put my first one in. Why would you ever worry about stuff like that? 🙂 I put in the small 90 gallon one as a test one to make sure I could handle it before I went larger (I didn't really go much larger as it turns out). But a pond sounds much scarier than it is, it's pretty easy to maintain once you get the
Hi! I've also been having string algae problems with my pond and I'm looking for a way to get rid of them. A Pond Blog article advises to use beneficial bacteria to eliminate string algae. Is this different from barley straw? Do they offer the same results?
Hi Jane,
No, I don't think the beneficial bacteria they are referring to is the same.
Beneficial bacteria is an important part in keeping a good balance in the pond, along with fish and plants. A good balanced pond will prevent all types of algae growth. But when algae growth starts to take over, that's where the barley straw comes in.
When string algae is
Amy;
We are really impressed with your page, and now have new direction to clear the water in our problematic 250 gallon pond. I will relay our progress and success as it happens, along with any new information we come across in hopes to help you or your followers. Thanks, Tomm
Hi Tomm!
Thanks, glad you found my blog. Hope this method will help you keep your pond clear. I would love to hear about your progress, and how it goes for you. Good luck!

Will hydrogen peroxide hurt the fish?
It might if you pour it directly on them. But, if you use the recommended amount and pour it over your fountain or waterfall to disburse it, it won’t hurt the fish. I’ve been doing this for a few years and have never lost any fish.
I bought property and had an overgrown pondan area. We got excited my birthday came an my nephew cleaned ut pretty good then added fish. Onjy gad it for three weeks.already see grreen hairy stuff ansludge too.with aiiwe have to do I need some easy steps I have no pump just running water.please help me out.don't think its 500 gallons but Huerta guessing.I sure want to enjoy it.help needed!
I would start by taking a brush and cleaning out some of the algae (like I describe above). Next, I would add hydrogen peroxide (I use 1/2 cup in my 90 gallon pond, so you can do the math for your pond). You said you don't have a pump, but do have running water so just pour the peroxide over the area where the water is running into the pond. Or you can disperse it around the pond yourself.
Even with it being the middle of summer we just got our pond going again about 2 weeks ago with rebuilt sides and stepping stones around side because our small boulders on side of pool kept falling in. Our water garden is in the sun from noon until sundown we are trying to get more plants and fish. only have 3 small orffs and 2 gold fish now. will get more if these do ok for a couple of weeks.
Yes, I would add barley straw and treat with peroxide now. I leave barley straw in mine year round, refreshing it every spring. It certainly won't hurt to add it this late, and it will start to break down before winter. Next spring, add new barley straw. Hope this helps.
Amy
Which brand Hydrogen Peroxide are you using ? and what is the percentage Food Grade or Commercial – 3% or 35%
I just buy the generic brand at Target. It's 3%. I find it in the first aid section.
35% will burn skin and kill anything it touches! Use the 3%:)
Thank you, ever so much for this post! Couldn’t have been more timely . . . we bought our house in May and with it came a large koi pond (guessing about 500-600 gallon). It needs cleaning desperately and until reading your article I had not a clue how to go about it.
Wow, that sounds awesome Camille! I’m glad I can help. Enjoy your new pond!
Amy
Our pond is about 20 acres. A few years ago I read an article about making an island out of barley straw and planting things on the top of it to control algae. For a water area this large, that can get to be very expensive. I’ll have to organize all the neighbors who live on the water and see if they will all chip in. Maybe next year.
Wow, that sounds like it would be really cool. Time for a fundraiser. 🙂
We have a 4000-5000 gallon natural pond in our yard with several koi and comets. The string algae is always a problem in the spring. We’ve treated with barley extract a couple times but it didn’t seem to having long lasting effects and ended up adding the chemicals to control the out of control algae. We added several water plants which seemed to help some. Now that I’ve read your article, I’ll try the barley bale from my local garden center and the peroxide as well…it’ll be a lot more than a 1/2 cup 🙂 Thanks for the ideas!
Haha, yes you’ll definitely need more than 1/2 a cup for your huge pond! I hope the barley straw will do the trick for you, good luck!
i was wondering if timothy hay would work the same way. i have many goldfish in my 90 gallon pond. would the peroxide hurt the fish?
I was told that only barley straw works in this way. The peroxide doesn’t harm the fish, I use it in my ponds all the time (I have goldfish too).
How often can you add peroxide?
I would say once a week, or once every other week until you start to see the string algae dying back. But, if you have a ton of algae growth in your pond, try to remove as much as you can with a toilet brush (or other brush) before treating your pond with hydrogen peroxide. Otherwise, it can be really hard to clean the pond once the algae starts dying.
Hi Amy! I am excited to try this!! Gonna purchase some barley straw today! I was using chemicals, and wanted to find a natural way of clearing my pond of guck! Thank you for this post!!! Aloha, Jen
Great, glad to hear it! Hope it works as well for you as it has for me.
I am thinking of doing a couple of recycled tire ponds in my backyard but I have dogs and I live in MN so breeding bloodsucking mosquitoes is a problem. Do you have any recommendations? I don’t plan to do fish as they wouldn’t survive the MN winter in such a shallow area. Will I need something to keep the water moving? I’d use chlorine but it’s not safe for the dogs. Any suggestions would be great
I am also in MN and I use a stock tank heater to keep the water in my ponds from freezing to the bottom. Mine are in the ground though, so if yours is going to be above ground, the stock tank heater probably won’t keep it from freezing. I recommend buying inexpensive goldfish. They will eat all the mosquito larvae and are cheap enough that if they don’t survive the winter, you can replace them every year (they’re like $.10 or $.25 cents a piece at the pet store). But, the goldfish will hibernate and survive the winter as long as the water doesn’t freeze solid. I’ve had them survive 5+ years in my small garden pond.
I was wondering if hydrogen peroxide will hurt koi or goldfish in my pond?
Thanks
No, it won’t hurt them as long as you stick to the recommended amount. I have goldfish in my ponds.
hi
we have a pond which has 2000 gallons of water. We r having trouble with the algae it’s like a fine dust floating around n it will just brush of rocks n sticks to plants will hydrogen peroxide help this n do u kn what kind of agae it is
thanks
laurie
Sorry, I don’t know what type of algae it is, but the barley straw/peroxide trick should work the same for any type of pond algae. Make sure to skim the algae regularly while you’re treating the pond, that will get rid of it much faster. Good luck!
can I Use wheat?
No, it has to be barley straw.
When you brush the algae off though it just goes straight into the water, which I doubt is good for the fish? Having this problem myself when cleaning my fountain, all the muck goes straight in. Any ideas?
True, but that’s why you have to rinse the filter on a regular basis. That will help clear out the algae.
I have a 10ft. Height waterfall leading to my koi pond and ends up in a gazebo. I live in a tropical country. I don’t think we have barley straws here. Can you suggest anything else?
Hope you can help. Thanks.
You can buy barley straw online. I’m not sure if you can shop on Amazon from where you live, but here’s the barley straw that I buy… Barley Straw
I also mentioned a few products you could try in the post above, here’s a list of a few things I’ve also used…
(FYI, these are affiliate links)
If you can’t order this stuff online, then I recommend going to your local garden center and ask if they carry any of these products, or if they know where you can find them.
Using this method, would the water be safe for my dogs to drink?
Well, I don’t have dogs so I’m not sure how “safe” pond water is for them to drink. 😉 But you can feel safe knowing that you’re not putting any yucky chemicals in the water that could be harmful to your dogs if they drink the water.
Wow! Interesting. I did not know this. TFS! Visiting from the Creative Corner
You’re welcome, thanks for stopping by!
We moved last year to a house with a tiny pond with a big algae problem. I have just been removing it manually so I’m happy to give this a try. thanks.
BTW cleaning the pond with a toilet brush is way more gross that cleaning the toilet with the pond brush in my opinion anyway!
Awesome, hope it works well for you.
LOL, I agree! Love it.
I hope to some day get to have a little pond in a backyard somewhere(we’re in a duplex right now). This is good info to know. I’ll also pass it along to my mom whose pond is generally getting a bit of algae in it by the end of summertime. Thanks so much for the tips!
Awesome, thanks! You’re welcome. 🙂
I have a 250gal pond with Koi in it. I’m constantly having to change the filter. We’d like to do away with the filter entirely and only use an aerator. We want to cut down on the maintenance and use only barley straw and lava rocks. Any suggestions and would this work?
Sounds like a great idea. I would definitely talk to someone at your local nursery (where they sell backyard pond equipment) and get their advice. Sorry, but I don’t have experience doing that. 🙂
I have a house that came with a pond and had no idea what to do with it. This info is right on time! Thanks!
Perfect! Thanks for stopping by!
Thanks for sharing this information at Inspire Me Monday link party. I have been having this problem for years. I am featuring you this week, come by and check it out. http://www.farmhouse40.com Monday at 9 a.m. EST.
You’re welcome. Thanks so much for featuring my post!
I have just brought barley straw off of the internet for the pond, to eliminate green/algae;
it is already in nets; does it need anything added to it or treating with anything first? Do I just put it in the pond and leave it? Is it harmless to fish and pond life?
You just need to put it in the pond and leave it. It will eventually sink. No, it’s not harmful, it’s completely natural and safe to use.
Hello I just recently put in a small pond (its just the tub that you buy with the kit – I bought used) I scrubbed it before putting in the ground and doing my landscaping. I do plan on buying the pump to do a waterfall but for now it’s just there. I bought some feeder goldfish, a albino frog and 2 fantail gold fish but unfortunately we cant see them cuz the water is cloudy but way too soon for algea. Would the peroxide work?
You can definitely give it a try, it should help. But it would work best of you put a pump in there (even it it’s just a bubbler) to aerate the water and help to circulate the peroxide.
Hey Amy great story I have a natural alternative that won’t cost a dime
I live in the Ohio Valley, New Albany, IN five mins across the Ohio River from downtown Louisville, KY. Anyway, the sun is strong here and algae is problem if your pond is not covered with 60% of the top in shade whether you use floating plants or some sort of coverage to prevent the algae blooms. I open and close peoples ponds and keep them clean as a side job. After doing some research I learned you can take simple branches of weeping willow depending on the size of your pond I d say about one branch for every 10 gallons of water. The best way to remove the branch fromthe tree is by making a clean cut with a knife or razor blade and this will not harm the tree it will regroup the branch. By making a clean cut with a sharp object it does not disturb the water vein in the branch like it would if you used shears or scissors. That would pinch and close off the water vein. Place your cut end of the branches into your pond, bird bath, fountain, etc. Around 5-6 days you will notice roots forming from the cut ends and those branches will now start taking in nutrients ffrom the water and starve and deplete the algae from getting them which in turn kills the algae and now you have starts of new willow trees that you can plant in the ground. You can leave the branches in the water for as long as you like. But the best way to keep the algae out long term is to have 60 % of your water feature shaded either by floating plants, a roof, or by using pond dye. Hope your followers try this inexpensive treatment and raise new willow trees from it. Enjoy your day evryone! Chris Pendleton-New Albany, IN facebook.com/stylinstud
Wow, that is so awesome! I love this idea and I’m totally going to give it a try. Thanks so much for sharing Chris!
Now all I have to do is search for a willow. I will try it. It makes sense to me. Because of willows’ penchant for growing into plumbing problems, people don’t use them much anymore for landscaping. I grew up having tea parties and other pretend parties under one huge shady willow.
One tip from me: If you have ailing trees, roses and other shrubs, planting willow slips around them usually cures them. It has medicinal properties for plants.
Interesting, thanks for the tip!
FYI when the barley straw decomposes it actually produces H2O2, so skip the middle man and go straight to the H2O2. For small ponds, the 3% stuff is fine. For larger ponds, it’s cheaper to get the 27% (often sold as chlorine-free pool shock). When H2O2 breaks down, it forms H2O (water) and O2 (Oxygen), so it is safe once it breaks down. The key is to make sure it breaks down! This is more of a factor of how much organics/algae you have as opposed to total volume. If your water is brown, with a lot of leaves and algae, the H2O2 will break down quickly. If your water is mostly clear, start with minimal doses, and repeat every couple days if needed.
Some reading from people way smarter than I!
Thanks for adding your tips!
I used charcoal in mine. After it settles it works great.
Cool! Is it a charcoal filter, or do you just drop bits of charcoal in there?
We just bought a house on a shortsale..It has two ponds. One in a walled in area(which has an electric filter which clearly has not been turned on in years) and the other is about 50 feet by 40 feet. Also is in sad state. I will immediately get the barley, a skimmer net, H2O2, and some goldfish. There are cat tails growing along the bank in areas. Do we need an aerator? Your article is superb. Thanks so much
I would recommend you test the water in your ponds before you add fish. You might have some work to do to get the water clean enough for them to survive. Here are some test strips that you can use… Pond Test Strips Goldfish are cheap, but it’s not worth the effort of adding them to the ponds if they’ll only die shortly after. 😉 I would start with that, and then go from there. Once you get the water healthy and ready for fish, then you can look into buying an aerator.
Hi Amy
I don’t know if you still read these emails.
I live in Australia on the Sunshine Coast. This area is tropical but has cool winters.
We just put a tyre pond in. I have 4 gold fish at the moment, some water plants and stones at the bottom of the pond. I have a small solar water fountain which only works during the day. This will be made into a waterfall going from one pond to the next- we used two tyres. My goldfish are very happy but I can feel the sides of the pond starting to get a bit slimy. I will definitely try the hydrogen peroxide trick and get some barley straw. What a wonderful idea.
I will save your site onto my desktop.
I will also be looking at buying some fish that eat mosquito larvae which is also a problem here in Summer. If I get some more water plants will they also help to keep the pond healthy?
Kind regards
Sounds wonderful! Goldfish eat mosquito larvae, so you should be fine there. Yes, adding a few plants will also help to keep the pond healthy. I have hardy water lilies growing in mine, they’re beautiful!
There are fish that eat algea which is great but they cannot tolerate cold weather. You can buy them in most stores that sell fish. Snails eat algea too. There are some very large snails that can be bought for outside ponds. They are difficult to find though.
Thanks Sara. Great tips! I have thought about getting one of those bottom feeder fish that eat algae, but I would feel terrible when it died over the winter. I think it would be really hard to find it in the pond to take it out in the fall. LOL!
Hi Amy,
Great thread. I have a 250 gallon pond. My questions is: can one put too much barley in the water? I’m noticing most commercially packed barley bails are for 500-1000 gallons. Do I need to reduce the size or can I put a barley pack designed for a 1000 gallon pond into my 250 gallon pond? Thanks in advance!
I reduced the size of the straw bales for my small backyard garden pond (as you can see in the photos above). I don’t think you can add too much barley straw… but I thought it would be wasteful (and ugly) to use the huge straw bale in my tiny pond. Breaking it apart means I get more uses out of one bale.
Hi Amy, We are building a natural pond and need some advise. We live in South America 2.800 meters over sea level rains a lot but the sun is strong too year round? Can you please suggest plants to buy and any other tip will be welcome.
Best regards
I grow water lilies in my pond. They are very cold hardy, and they flower every year. I’m not sure what you comparable growing zone would be in, so it’s tough to recommend plants that will grow well for you. But some common pond plants are water lilies, cattails, papyrus, water irises, taro, water hyacinth, canna lilies and umbrella plant. There are lots of water plants to choose from though, some are hardy and some are tropical (not cold hardy). Also, check your local garden center to see what they recommend.
Thanks!
We have tried any amount of barley straw in our smallish pond and found it absolutely useless!
Maybe there’s a special kind of barley straw and you need to know the codes/passwords/special handshakes to obtain a supply, but the stuff we bought from our garden centre changed nothinh.
The toilet brush tip is a good one though. I have recently used an industrial style wire brush with remarkable results..
Most of the blanket weed has now gone, but unfortunately the goldfish have developed rust spots..
I’m not sure what kind you bought, but this is the type that I buy… barley straw. Keep in mind that it takes a while to start working, so you won’t see any results right away. The barley straw won’t work until it starts to break down, and could take a month or so to start working.
Hi Amy,
What kind of waterfall pump do you recommend for a small pond and where can I find one? I don’t want to buy an expensive one.
Thanks,
Tina
It depends on the size of your pond, and the height of your waterfall (if you have one). This is the pump I have in my small pond (which is about 120 gallons). The waterfall is about 3-4 feet from the bottom of the pond, so this one is more than adequate, and works great for me! It pumps 330 gallons per hour, and works great for waterfalls under 7 feet tall.
Hi,
Would the following be a good one that includes everything?
https://www.amazon.com/dp/B0068MW50M
Thanks,
Tina
That one would work great for a small pond, and comes with a fountain attachment rather than a waterfall. But, if you have a waterfall, you can still use it, you just have put a tube attachment on there instead of the fountain attachment.
This is awesome! I have to try both ideas thank you for sharing 🙂
You’re welcome!
How often do you treat your pond with peroxide?
I only use the peroxide as needed before the barley straw starts to decompose and work it’s magic. I probably use it about once a week or so.
The wife and I spent FIVE hours clearing out our small fishpond. There was four inches of sediment on the bottom (which stank!). Took out the irises, took out the lily pads..
We cleaned it all out, put pebbles on the bottom, filled it up and re-introduced the five goldfish.
First three days lovely and clear, and now beginning to get a very slight haze in the water..
We don’t over feed the fish, we only have two plants in there
My guess is it’s a combination of rainborne/windborne dust plus fish poo.
I am going to try rigging up two solar powered pumps to draw the water through a home made filter and re-cycle clean water back in.
Or I might fill the darn thing in!
Yes, all of that muck is caused by fish waste, and also bugs, leaves and other debris that falls into the pond daily. It’s a good idea to get into the habit of skimming the debris off the top of your pond regularly. This is especially important in the fall as the leaves are dropping. Adding a filter will help a ton, along with the barley straw treatments I’ve described above. Good luck!
I am planning on putting in a small pond on my patio garden. I really like the idea of using a natural algae remedy. I wonder, do I need to wait until there’s algae in the pond to use the barley straw, or could I put the barley straw in the pond from the beginning to keep the pond clean? Does it work as the algae is forming (I’m assuming, since I live in a hot climate, that there will be algae very quickly?) I’ve been living in rentals for 10 years and I’m excited to have my own space to make a garden. Thank you for your advice.
You can put the barley straw in from the beginning, it won’t hurt anything. Have fun with your new garden, how exciting!!
We have emptied our small pond of sludge etc, cleaned it out wire brushed the blanket weed off the sides, put largish pebbles on the bottom and installed a small pump. I made a simple filter out of a plastic swingbin, using aquatic grade fine foam and an old fine weave cotton cloth folded up to catch the tiny particles.
This is working great for us. No more murky water, just filtered re-cycled pond water..
I put the pebbles in so that every now and then I can use a water hose to stir up the junk on the bottom and let the pump filter it out.
Hope this helps.
Can you use this in stock ponds? i have a pond that is cover with green stuff. we don’t have livestock using it.
I don’t see why not, since it’s non-toxic. But, I’ve never read anything about it, so you might want to do a bit of research about that first.
I have a unique problem. I have planted plants in the bottom of my 6ft pond. THe water turns over every 1.5 to 2 hours and I use a UV clarifier with a bead filter. The koi have shredded my plants and I am unable to produce “clear” water due to the debri left behind. HOW or what do I do to “clear” my water?
If the plants are still in there, and the koi are constantly shredding them, I don’t think you’ll ever be able to clear it. I would remove the plants, and then use a filter that will pull the debris out of the water, and keep cleaning it. Also, use a net to fish out as much of the debris as you can to help speed it up.
