Our pond gypsum helps clear muddy water by bringing suspended clay particles together so they settle to the bottom. We screen it through a series of screens to remove most large chunks, producing a fine powder that mixes readily with water for even application. A small amount of residue is normal. Choose gypsum intended for pond application rather than repurposed sheetrock, which can contain paper, coatings and other materials unsuitable for that use.

Yes. Start with our Gypsum Pond Clarity Test to see how your own pond water responds before committing to bags or a pallet. It’s a simple, inexpensive step that helps you make an informed purchase. If the sample clears, you can move forward with pond gypsum with confidence that your water responds to the application. Follow the bag’s starting rate and assess your pond’s response before applying more.

Start with 5–10 40 lb bags of pond gypsum per ¼ acre of pond surface area, following the bag’s directions. Use the higher starting rate for severely muddy water or heavy clay. Mix the gypsum with water to make a slurry, distribute it across the pond, and assess the response before additional applications. Your pond may require more than one application to achieve the desired clarity.

Start with our Gypsum Pond Clarity Test to see whether your pond water responds to gypsum before investing in a full application. Mix our pond gypsum with pond water in a bucket, using a paint mixer to create a slurry, then distribute it across the pond. Follow the starting rate on the bag and assess the water’s response before applying more. For watershed ponds, you can also apply gypsum along the bank where rainwater runoff enters. Many of our customers use this method so incoming runoff carries gypsum into the pond. Many pond owners find that two to three applications per year are needed before they see longer-lasting improvements in clarity. Let your pond’s response guide repeat applications; continued muddy runoff can bring in new sediment.
