Keep your natural pond, dugout or lake vibrant all year round by starting off the season right with ClearLake Cold Water Clarifier. Because this formula is designed to work in cold water, it improves water quality, maintains water clarity and digest organic matter such as leaves and twigs early in the spring (and also late in the fall) when other pond clarifiers are just not effective. This means you can add ClearLake Cold Water Clarifier weeks or months earlier than typical pond clarifiers.
Get the upper hand on cloudy water poor water quality by treating your pond early this year.

ClearLake Cold Water Clarifier is a blend of naturally occurring beneficial bacteria designed to work in conjunction with the natural bacteria and enzymes found in your pond. However, this highly concentrated formula contains billions of psychrophilic (adapted to grow in cold temperatures) beneficial bacteria that digest organics in your pond, improving water quality and clarifying water in temperatures as low as 35 F / 1.7 C. Adding ClearLake Cold Water Clarifier supercharges your pond’s ability to combat excess nutrients and break down leaves, twigs and other organic matter in cold water and reduces the chances of algae blooms when the water warms up.
Ideally ClearLake Cold Water clarifier should be used when water temperatures are between 35 – 50 F / 1.7 – 10 C, when typical pond clarifiers are inactive. Perfect for early spring application to kick start your pond for clean clear water during the summer months. Then treat again in the fall to help break down and digest excess organic matter that has accumulated during the summer as well as any tree leaves that have fallen in to the pond late in the season.
ClearLake Cold Water Clarifier is most effective in water temperatures between 32 F – 50 F / 1.7 C – 10 C, making it perfect for early spring application. Get a head start on clearing your pond water and digesting last autumn’s fallen leaves and twigs by applying your first application right after the ice melts from the surface. Even in the frigid water, the cold loving bacteria will go to work digesting accumulated leaves and twigs and improving water quality. ClearLake Cold Water Clarifier also cleans and clears the entire water column improving the look and health of your pond.
Cold Water Clarifier is especially effective for ponds that have high volume springs that add cold groundwater to the pond all year long, keeping the water temperature cool even in the summer.

Cold Water Clarifier is available in 2 convenient sizes. The 8 lb pail contains 16 bags/packs and the 24 lb pail contains 48 bags/packs. Each 8 oz dose is conveniently packaged in water-soluble bags for easy application. Simply toss the appropriate number of bags for your pond into the water and let the bacteria go to work.
Autumn can be a difficult and frustrating time of year for pond owners. You’ve worked hard all summer to maintain your pond and kept it looking great … but then the tree leaves fall and quickly sink to the bottom. These leaves, twigs and branches are often very difficult to remove and if left in the pond, they add unwanted organic matter that will eventually contribute to poor water quality and clarity.
Luckily, you can proactively treat your pond with ClearLake Cold Water Clarifier in the fall to help digest leaves and other organic matter, making spring maintenance much easier by minimizing the amount of decaying matter left in your pond.
For best results do NOT apply ClearLake Cold Water Clarifier water soluble bags in the same area of the pond. Throw the prescribed quantity of water-soluble bags into the water body so they are dispersed evenly in a grid-like fashion.
Initial Application: 6 lbs. Per Surface Acre of Water
Maintenance Application: 2 to 3 lbs. Per Surface Acre Every 2 Weeks
Goldfish make ideal pets for small ponds because of their modest size. They typically grow 8”- 10" long, although they can occasionally get bigger. The best types of goldfish for outdoor ponds are Comets, Sarasa Goldfish and Shubunkins.
