What is green water?
The presence of a large population of uni-cellular algae causes green water. This algae is the pondkeeper's nightmare. "Pea soup" conditions caused by algae are unattractive and threaten fish health by using up oxygen. Green water occurs in most ponds and can be very difficult to eliminate.
When green water is pumped through the UV Clarifier, the algae are exposed to ultra-violet light. As they pass around the UV lamp, these particles are flocculated (clumped together). Water circulation carries them to the filter, which removes them, leaving behind only CLEAN WATER.
