PondMAX Algae Block


This block is used as a preventative, or when algae first appears, or after cleaning an algae infested 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 by hand before treatment, and aerate the water after use. Distribute products evenly throughout the pond.


Add one 15g piece per 200L of water. DO NOT OVERDOSE

Place pieces to cover all areas of the pond.

Do not contaminate streams, rivers or waterways with the chemical or used containers. Do not use more than the recommended dose as fish and plants may be harmed or damaged. DO NOT use in ponds containing fish intended for human consumption
