API POND SIMPLY CLEAR Pond Water Clarifier provides a two-step approach for an incomparably clean and clear pond. API POND SIMPLY CLEAR Pond Water Clarifier quickly clears murky, cloudy pond water, and it breaks down pond sludge for maximum cleaning power. API POND SIMPLY CLEAR works by aggregating tiny suspended particles in pond water to form larger clusters which fall to the bottom of the pond where they are consumed by a super concentrated blend of beneficial bacteria. This solution is safe for fish and pond plants, as well as surrounding wildlife and pets, when used as directed. Exclusively for freshwater ponds, this solution is most effective when used every two weeks. With API POND products, it’s easy to keep a beautiful pond. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your pond. API POND Pond Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as koi, catfish, perch, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your pond. Make sure to use all products as directed in order to ensure the best results.

Safe and effective
It took a little over a week, but I now have really clear water in my fish tanks. I put a little less than a capful in a 10 gallon tank, and the water has been clear since. Itâs natural, and with as little as I need it will last a very long time.

Clear Pond
This solution was a lifesaver for my stock pond. It controls algae wonderfully if used as directed. It’s super easy, and keeps my fish healthy all season long.

Ruined pond water
Ruined my pond. My pond was well balanced and I wanted to use this just as proactive treatment and used lowest dose and it turned my clear water green, foamy and murky in 24 hours . I can’t even see the fish and hoping they live long enough for me to find a way to clear up the water
Sue –
This stuff is amazing! Marked improvement after 24 hours. Water crystal clear after 2nd dose. (Before starting this treatment it looked like thick pea soup and you couldn’t see more than 5cm down.)Fish didn’t seem at all bothered by it (and I’d got my measurements wrong and added in more than I was supposed to!)
Amy –
Great and nice to have a natural product to keep the pond healthy!
Brenda –
I needed to enhance water clarity in one 2100-gallon pond another of around 300 gallons. I’d had a very bad experience with a different product from another company and lost all my baby fish, along with injuries to my adults (damage to their slime coating). But the water badly needed clarifying so I could see exactly what was in there. Simply Clear worked beautifully! There was no fish loss. I could see right to the bottom of the larger pond. The smaller one is in a shady area so it’s always dark but the water flowing through my little aeration hose is clear too. I will use this again and buy more when it runs out.

Cleared up my small pond in a few days. I only need to add 6ml at a time so will last quite a while.
Harley skiier –
kept the pond relatively clear until the heat started rising and then the algae bloom took over.
