Tested and proven. GreenCut anti algae powder gets rid of green water by coagulating the microscopic one cell algae which
causes the water to turn green.
This 30g bottle can treat up to 30 tons of water depending on how green the water is.
Result can be seen within 24 hours. But like all algae destroy it is only a temporary solution. Green water may return if biological conditions in the pond are not rectified.
Sunlight, pond waste and inefficient biological filters are the cause for green water.
