I have a 7,000 gallon koi pond with 22 koi ranging from 12" to 30" in length. Average is 20". I'm a heavy feeder, I also feed twice per day. The pond is in full sunlight and circulates 8,000 gallons per hour via a 100' long 3' wide river with a 3' wide waterfall. What does all that mean. It means the water get's plenty of oxygen and sunlight and therefore grows green algae by the ton! The normal water color for the past 7 years has been pea green! I have lots of filtration, a huge UV filter and I've used hundreds of dollars of good bacteria. NOTHING kept the algae out for the past 7 years. ----> this year I decided to try a chemical to clear the water or get rid of the pond. I read everything I could find and decided this was the best chemical “experiment”: " poly oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride ". This chemical is packaged under several different names and a concentrated version can be purchased at swimming pool suppliers. (concentrated is 20%, much thicker, more like syrup) The chemical kills algae AND causes it to clump and float to the surface as foam. It will clog your pond filter in a blink because of the clumped foam dead algae. Be prepared to clean the filter often. The chemical is "consumed" as it kills algae and my water was so green I added 7 times the dosage over a period of 3 weeks. The color tuned from pea green to a gray green slowly. I had to clean the filter every couple of days for about a month. ===>>> the water is now crystal clear. I now add about 3 ounces every 2 weeks and the water stays crystal clear. Every time I add there's a little foam on the surface, the filter clogs up within 48 hours, I clean it about 60%, not 100%, and I'm good for another 2 weeks. I'm very pleased with the results, ===>> How did the fish and plants do? It never phased them one bit. Not one bit. They didn't come up gulping for oxygen, it didn't faze any of the many frogs or billions of snails that inhabit the river, NONE of the lilies or water lettuce or other plants were affected in any way. I don’t have any experience with other fish other than koi. This is the chemical, sold under several different names: " poly oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride " The dosage will vary by vendor depending on the concentration. The 3oz per 7000 gallons every two weeks I use is a 20% concentration I purchased at a swimming pool supply store sold under a different brand name. I have tried three different brands of this chemical (including this one) and they all work exactly the same. The only difference is the dosage which varies based on the concentration, ranging from 4% to 20%. Attached, 2 pictures, before and 45 days later, after. Review: Great Product! - Great product, cleared my pound of an insane amount of hair algae in 3 days. Water lilies and fish show no signs of stress. ## Features - API POND ALGAEFIX – Helps resolve algae problems and controls the formation of new algae; works fast without harm to fish, aquatic plants, surrounding wildlife, or pets when used as directed; includes 8 fl oz for treating up to 2,400 gallons - Fast and Effective – Controls most types of algae, including green water (Chlorella), string and hair algae (Cladophora), blanket weed algae (Oedogonium) in ponds, koi ponds, and fountains - Safety First – EPA-registered and copper-free formula is safe for fish and plants when used as directed and won't disrupt beneficial bacteria or accumulate in pond sediment - How to Use – Ensure that the pond/fountain has vigorous aeration; mix thoroughly into the pond/fountain and disperse evenly; repeat every 3 days until algae is controlled, then dose weekly to keep ponds/fountains clear and reduce maintenance​ - Why API Products? – For over 60 years, we've been a leader in the aquatics industry, developing and perfecting products and solutions for indoor aquariums and outdoor ponds.

Water lilies and fish show no signs of stress. ### ⭐⭐⭐⭐ Great stuff; works well with no adverse effects *by T***M on July 18, 2025* Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation. ## Frequently Bought Together - API POND ALGAEFIX Algae Control 8-Ounce Bottle - Summit Clear-Water Barley Straw Pond Treatment, 2-Pack, Treats upto 2000 Gallons, 1000 Gallons per Bale - API POND-ZYME SLUDGE DESTROYER Pond Cleaner With Natural Pond Bacteria And Barley, 1-Pound Container --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.bo/products/5719295-api-pond-algaefix-8-fl-oz-pond-algae-control-copper](https://www.desertcart.bo/products/5719295-api-pond-algaefix-8-fl-oz-pond-algae-control-copper) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-04-22*
