All ponds suffer from algae growth at some point and many species of algae cause green water. A thick 'pea soup' effect robs your pond, fish and plants of light, oxygen and vital nutrients. This can be a real problem in the summer months and having a treatment to hand can make life much easier.
Swell Anti Green Water treatment enables you to quickly create clear water without affecting the pond's biological balance. It binds the algae cells together for easy removal by the filter and keep your pond looking good.
Add 10ml per 450 litres (100 gallons) of pond water.
