Consumes Phosphates and Nitrates Clarifies water of organic and inorganic materials Quickly clears pond water This triple action formula acts fast clears pond water and breaks down sludge and offers a long term solution to un clear pond water. Pond Simply Clear is a fast acting bacteria that feeds on small size organic materials that often cause cloudy water conditions. As the bacteria rapidly grow they shed their outer coating which acts as natural flocculent clumping fine particles. As the fine particles clump together they either drop to the bottom of the pond or are removed by the pond filter. Once the particles are clumped together the bacteria have a concentrated food source further reducing the causes of cloudy water conditions. The bacteria require phosphates as a necessary food source eliminating it from the water. The fast acting bacteria are extremely efficient at breaking down dissolved proteins that are associated with poor water clarity. Simply Clear bacteria will quickly clear pond water and digest and eliminate the floating particles.
