Jebao PU 11w Pond Clarifier Kill Green Water Garden Koi Fish Ponds Working Used

Jebao PU - 11 Pond Water UV Clarifier - Used but working order. The water must be pumped through the unit and not gravity fed (pump not included). The algae, causing green water, are made to clump together (flocculate) by the UV (ultra violet) light so that they can be sieved out of the water by a filter to give clear water.
