UltraClear Sludge Digester – Pond Sludge & Muck Remover for Outdoor Ponds (Treats Up to 32,000 Gallons)

Whole-Pond Clarity with a Single Pour

Ponds accumulate organic waste from fish activity, fallen leaves, and decaying debris. UltraClear Sludge Digester changes the game by delivering a liquid blend of beneficial bacteria and enzymes directly into the water column, working where the muck is heaviest. The result can be a calmer, more balanced environment that supports clearer water and healthier aquatic life without harsh chemicals.

How Sludge Digester Works

Unlike tablet or pellet treatments that sink and stay in one area, Sludge Digester disperses evenly through the entire pond—from surface to sediment. This early, uniform distribution helps target the organic load wherever it sits, from shallow shelves to deeper coves, delivering robust action where it’s needed most.

The product’s proprietary blend targets the main types of organic waste found in ponds: fish waste, dead algae, leaves, decaying matter, and accumulated bottom muck. Over successive treatments, you may notice a gradual reduction in the muck layer and improved water movement, which can contribute to better oxygen circulation.

Key coverage and dosing benefits include a straightforward, no-mess approach: pour and go. One ounce treats 1,000 gallons, and a single gallon covers up to 128,000 gallons of pond water. This high-concentration formula makes it possible to treat larger systems efficiently, reducing the need for frequent re-dosing in bigger ponds.

Simple, Safe, and Seasonal

Sludge Digester is 100% natural and safe for fish, koi, aquatic plants, birds, wildlife, and pets. There is no harsh chemical presence, and the pond remains swim-ready immediately after application. For best results, apply when water temperatures are above 50°F, and consider pairing with UltraClear Cold Water Blend during cooler months to help maintain balance across seasons.

In practice, many pond owners find this product easiest to manage during routine maintenance: measure, pour, and move on to other pond chores. Its liquid form reduces guesswork, and its full-pond coverage helps you avoid patchy improvements that don’t reach every corner of the water.
