OASE AquaActiv AlGo Universal Total Algae Control is a liquid treatment for controlling string algae or slime algae in a pond. When used correctly it is safe for pets, plants and wildlife. It works by inhibiting the metabolism of the algae, so it basically stops it having the energy to grow and reproduce. It takes 2-3 weeks to work.We always recommend you avoid using algae treatments in spring when wildlife like tadpoles are relying on there being some algae to nibble on.
