Blue Planet Pond Clear controls most algae common to ornamental fish ponds and prevents algae from reappearing

Blue Planet 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 is caused by dead and decaying algae and can lead to fish mortality. To prevent oxygen depletion, remove heavy algae growths mechanically before treatment.
