I grow water plants on the steps. The main problem I have is with a thin dark green coating of algae on the pond (concrete) walls and the floor. The water is slightly cloudy, but has no floating algae on the top. Right now, when I v…** A: First, we do not recommend its use with turtles, since it has never been tested on them, and they have skin that they can absorb chemicals through. Second, if the algae you are referring to is actually short like hairs, this is a beneficial algae called hair algae, and unless there is an overabundance of it, we do not recommend killing it all off. It provides food for animal life, and helps to filter and balance the pond. And last, it might be more cost effective, and healthier for your animal life to try barley straw pillows instead as this will help control algae in an all natural fashion and has been known to be very effective in properly maintained ponds. If you have more questions, please give the Tetra Consumer Relations Team a call at 1-800-526-0650. **Q: What chemicals are in this product? I cannot read the label of the active ingredients.** A: Thank you for asking! The active ingredients are: poly oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylene dichloride. These ingredients make up 5.4% of the formula. The other 94.6% of ingredients are inert. We hope this answers your question! For more help contact Tetra at PHGAmazon@spectrumbrands.com. We are happy to help! **Q: What's the concentration of the active ingredient?** A: Hello David Slack,This product is made up of the following ingredients: Poly Ethylene 5.4%, Inert ingredients 94.6%. **Q: How long on average does it take to start working? Our pond is 125 gallons and pretty green right now. There's no visible string algae.** A: Hello SDB!This is a slow moving product, so it won't start clearing for at least 24-48 hours. However, give it a full 72 hours to do its job before deciding if you need a second treatment or not. If the pond is heavily stocked or has not had a recent partial water change, we recommend changing out around 25% of the water, and then applying a second dose. Don't forget to check your filters and clean them out as necessary, and remove any dead algae from the pond to prevent oxygen loss and toxicity issues. ## Customer Reviews ### ⭐⭐⭐⭐⭐ will purchase again *by A***R on March 1, 2026* works great on keeping the pond clean of algae ### ⭐⭐⭐⭐⭐ Excellent product works well in my shallow pond *by J***. on May 4, 2025* Works great, follow directions exactly Takes care of floating and submerged algae ### ⭐⭐⭐⭐ Stuff works! Review my photos. *by B***E on April 26, 2016* Please check out my before and after photos I have uploaded. I have a 1,800 gallon pond with over stocked goldfish and two Koi fish left over. For two years I've been researching and battling and whatever trying to figure out what to do. I got away from a 600gph pump with a pre-filter and a 6 gallon bio filter. I bought a 110 gallon horse stock tank and a Pond Master 1,800gph pump together with the Tetra Algae Control treatment. I tried the pre filter to protect my pumps but the String algae loved the filter material and grew on it in 12-hours. I removed the prefilter from the pump and took (2) POND BOSS SQUARE PLANT BASKETS #DPB10 and placed my pump inside two of these plant baskets and zip tied the two baskets together buttend-to-buttend and my pump hasn't clogged in over 2 weeks and have not loss any water flow or pressure since. For two years I've been battling Green String Algae. This is the only time I've been able to see the fish below the surface and the pebble stones at the bottom of my pond. IT IS EASY TO OVER TREAT YOUR POND AND KILL YOUR FISH. Be confident how many gallons your pond is. I "under treated" and still got good results. I had to clean my filter immediately as the Algae Control along with UV Clarifier and the filter media caught all the dead algae and my "stock tank" biofilter clogged and over flowed. I got a 2-gallon water bucket. Filled it with garden hose water. Poured Tetra Control into the bucket. Then into the 110 gallon biofilter I assembled to create some dilution. And I poured it the opposite end of the outlet pipe. I recommend this product. In two days it hasn't killed anything. Not floating fish and no dead fish stink. I have more than 1 dozen frogs at night and they haven't died. ## Frequently Bought Together - Tetra 77188 Algae Control Treats 36000 gallons, 101.4-Ounce - Summit Clear-Water Barley Straw Pond Treatment, 2-Pack, Treats upto 2000 Gallons, 1000 Gallons per Bale - Kaytee Koi's Choice Koi Floating Fish Food, 10 Pound --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/4480860-77188-algae-control-treats-36000-gallons-101-4-ounce](https://www.desertcart.tn/products/4480860-77188-algae-control-treats-36000-gallons-101-4-ounce) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-31*
