Controls algae in freshwater ornamental fish ponds.
Pond Clear will not affect pond plants or fish when used as directed. When ponds are heavily infested with algae, oxygen depletion in pond water may occur after treatment. This caused by dead and decoying algae and can lead to fish mortality. To prevent oxygen depletion, remove heavy algae growths mechanically before treatment. Alage growth is promoted by phosphates from food, fish wastes and strong light.
Regular partial water changes and increasing shaded area of pond will discourage algae growth.
