Pond Muck & Sludge Remover - Treats up to 32,000 Gallons - 5X Concentrated Live Beneficial Bacteria - Reduces Pond Sludge, Muck & Odors - Safe for Fish, Koi, Plants, Pets and People

THE POND WORKS AGAINST YOU EVERY SEASON. SLUDGE DIGESTER WORKS BACK. Every pond accumulates organic waste — fish waste settles, leaves decay, dead algae sinks to the bottom — and over time that layer of muck gets thicker, shallower, and harder to ignore. It robs your pond of depth. It fuels foul odors. It stresses fish and disrupts the balance your water needs to stay clear and healthy. Most products attack this problem from the top down. Sludge Digester is different — it goes to work throughout the entire water column, from surface to sediment, delivering beneficial bacteria and enzymes exactly where the organic load is heaviest. FULL-POND COVERAGE THAT TABLETS AND PELLETS CAN'T MATCH Tablets and pellets sink to one spot and go to work there. That's fine for spot treatment — but it leaves the rest of your pond untouched. Sludge Digester's liquid formula disperses evenly across the entire water column the moment it's applied. Every corner, every cove, every shallow shelf along the shoreline gets full exposure to the same concentrated bacterial action. One pour, whole-pond coverage. No dead zones. One ounce treats 1,000 gallons — making Sludge Digester up to 5× more concentrated than leading tablet-based competitors. A single gallon covers up to 128,000 gallons of pond water. FORMULATED FOR THE FULL SPECTRUM OF POND ORGANIC WASTE Sludge Digester's proprietary enzyme and beneficial bacteria blend targets fish waste, dead algae, fallen leaves, decaying organic matter, and accumulated bottom sludge — breaking each down and reducing the muck layer over successive treatments, restoring pond depth and improving oxygen circulation naturally. SIMPLE DOSING. POUR AND GO. No scoops. No tablets to count. No mess. Measure and pour directly into your pond — the liquid formula disperses immediately on contact. Use 1 oz per 1,000 gallons every two weeks for problem ponds, weekly during peak summer months, and monthly for ongoing maintenance once your pond is balanced. For best results, apply when water temperature is above 50°F.
