All About the Product
Product description
Colombo Algisin – Powerful against string algae in koi ponds
Colombo Algisin effectively combats string algae in ponds, which can multiply rapidly, especially in strong sunlight, and overgrow plants and pond areas.
Through its special enzymatic mode of action, Algisin deprives the algae of essential nutrients, thereby stopping their growth. The string algae subsequently die off and can easily be removed from the water surface with a fine-mesh net.
Application ensures an algae-free pond and a stable biological balance, which significantly improves the water quality in the koi pond.
