Description
𝗔𝗰𝘁𝗶𝘃𝗲 𝗶𝗻 𝗖𝗼𝗹𝗱 𝗪𝗮𝘁𝗲𝗿 𝟯𝟮°𝗙–𝟱𝟱°𝗙: Most standard pond bacteria go dormant as water cools. This cold water beneficial bacteria formula continues working through the fall cooldown, unfrozen winter periods and spring warmup. If the pond freezes, the bacteria pause and resume after thaw.
𝗕𝗿𝗲𝗮𝗸𝘀 𝗗𝗼𝘄𝗻 𝗠𝘂𝗰𝗸, 𝗦𝗹𝘂𝗱𝗴𝗲, 𝗟𝗲𝗮𝘃𝗲𝘀 & 𝗙𝗶𝘀𝗵 𝗪𝗮𝘀𝘁𝗲: Concentrated beneficial bacteria target organic debris that settles on the pond bottom, helping reduce black muck, sludge buildup and unpleasant odors before they become a larger spring cleanup.
𝗟𝗲𝘀𝘀 𝗖𝗼𝗹𝗱-𝗦𝗲𝗮𝘀𝗼𝗻 𝗕𝘂𝗶𝗹𝗱𝘂𝗽, 𝗘𝗮𝘀𝗶𝗲𝗿 𝗦𝗽𝗿𝗶𝗻𝗴 𝗢𝗽𝗲𝗻𝗶𝗻𝗴: Use through the fall cooldown and again through the spring warmup to reduce the leaves, waste and organic material that accumulate while warm-season bacteria are dormant, supporting cleaner water and less bottom cleanup.
𝟭𝗹𝗯 𝗧𝗿𝗲𝗮𝘁𝘀 𝘂𝗽 𝘁𝗼 𝟬.𝟮𝟱 𝗔𝗰𝗿𝗲𝘀 𝗣𝗲𝗿 𝗠𝗼𝗻𝘁𝗵: Measure the labeled dose for your pond size and scatter the pellets evenly across the surface—no premixing or special equipment. Smaller ponds dose weekly because their lower water volume can carry a proportionally heavier nutrient load; larger ponds dose monthly.

Fall brings leaves and organic debris into the pond just as most standard pond bacteria begin to go dormant. UltraClear Cold Water Muck Remover is a concentrated cold water beneficial bacteria formula designed to work from 32°F to 55°F, helping break down the muck, sludge, fallen leaves and fish waste that settle on the pond bottom through fall, winter and early spring.
Reducing organic buildup during the cold months helps keep pond water cleaner, minimize unpleasant odors and make spring opening easier. If the pond freezes, the bacteria go dormant rather than being wasted. Once the pond thaws and the water returns to the active temperature range, they resume working.
Application is simple. Measure the dose for your pond size and scatter the pellets evenly across the water surface. Ponds up to 1,000 gallons are dosed weekly because smaller water volumes can carry a proportionally heavier nutrient load. Larger ponds are dosed monthly according to the label chart. No premixing or special application equipment is required.
1 lb treats up to 0.25 acres per monthly application. The formula is 100% biological, made without harsh chemicals and safe for koi, fish, pets, aquatic plants and wildlife when used as directed.
Use Cold Water Muck Remover through the fall cooldown and again through the spring warmup. Once water temperatures rise above 55°F, switch to UltraClear Muck Digester Tabs for continued warm-season muck reduction.
