Pond Stability® is designed to rapidly and safely establish the pond biofilter in new ponds, stopping gill-choking ammonia and nitrite, while also preventing sludge build up. Carefully formulated to cater to ponds specifically, Pond Stability® is a powerful blend of aerobic, anaerobic and facultative bacteria that breakdown waste organics, ammonia and nitrates. Non-sulfur fixing and completely non-toxic, Pond Stability® won't harm aquatic organisms or aquatic plants. Developed after a decade of research, Pond Stability® is a revolutionary product that surpasses competing brands, whose bacteria are highly unstable and require an exact range of temperatures, pH and organic loads to survive. Pond Stability®, however, is remarkably hardy and has a much broader growth range - even when other bacteria die, it just works harder and grows faster! Get 500 mL, 1 L, 2 L, 4 L or 20 L of it today!
