Clear Waters also contains algaecide which is the quickest and most effective way of killing algae straight away.
Unlike other algae and Blanket Weed treatments, Clear Waters will also work in the colder months if the Algae and Blanket Weed are actively growing. Clear Waters will yield results down to a water temperature of 4 degrees centigrade.
