Simply Clear is a stable fast-acting bacteria that feeds on small-size organic materials that often cause cloudy water conditions. As the bacteria grow their their outer coating acts as a natural flocculent clumping together fine particles. These fine particles then either drop to the bottom of the pond or are removed by the pond filter. The bacteria further consume these particles, further reducing the cause of cloudy water conditions. The bacteria in Simply Clear require phosphate and remove it from the pond water. Simply Clear bacteria will quickly clear pond water and digest and naturally eliminate the floating particles that cause water discoloration.
