The PondMAX Algae Block effectively prevents most algae common to freshwater fish ponds. HOW TO USE This block is best used as a preventative or when algae first appears or after cleaning an algae infested pond. Place pieces to cover all areas of the pond. Blocks will dissolve over 7-14 days depending on water conditions and circulation. If possible, control the amount of sunlight or artificial light to reduce the growth of algae. Repeat only when algae reappear. To prevent oxygen depletion remove heavy algae growths mechanically before treatment and aerate the water after use. Distribute products evenly throughout the pond.
