The Clear for Ponds autodoser pouch contains a powerful blend of Beneficial Bacteria, flocculant, algaecide and phosphate binder that clears cloudy, green and discolored water. Use only until water is clear, then switch to the Maintain for Ponds autodoser pouch for preventative maintenance. Use only as directed and as needed. Overdosing can cause harm to fish. One bag treats a 2,000-gallon pond for up to 30 days. Works with Aquascape Automatic Dosing systems.
