King British Green Water Control 100Ml
King British Green Water Control targets the tiny unicellular algae in your fish tank that cause “green water”. This special additive causes the algae to clump together and fall to the bottom of the tank, where they can be more easily removed. “Green Water” is unsightly, can clog filters, and can be bad for fish health, as it can reduce oxygen availability at night. For use in cold water & tropical aquariums. One 100ml bottle will treat 900 litres of tank water.
