Envii Pond Klear is formulated to target green water rather than pond sludge—the sediment in your pond made up of fish waste and other organic matter. If you’re looking to clear sludge from your pond, our Envii Sludge Klear is the most suitable product for eradicating sludge. However, we highly suggest purchasing our Envii Pond Klear & Sludge Klear bundle if your pond is plagued by both green water and sludge. By using the two together, you can achieve a healthier and more beautiful-looking pond, free from green water and sludge. Need advice on selecting a pond water treatment that’s right for you?

"Did the job (keep the filters clean ) having to do mine daily at first"
"I have had to use 2 applications of pond klear extra (2 x bottles) to my 4000 ltr pond and it now beginning to have an effect. I also purchased 1 x bottle of pond klear that I shall start using in the months to come. Appears to be working so a good product and delivered on time."
"Cracking stuff . Really cleared up the pond. Didn’t upset the plants or the fish 🐟 like the fact that you can just squeeze the bottle to measure the liquid out before putting it in the pond ."
"My pond is very green and will likely take some weeks of the weekly treatment to see a difference so I’m not able to comment specifically on the product. What I can say though is that I emailed the team about my problem pond & the fact I’m a novice pond keeper. Not only was the product recommended but also advice on what else I could do to improve the water with plants and specifically what type of planting, using a Ph tester etc. excellent service!"
