HOW OFTEN: For very dirty ponds, treat daily for 10 days, then once weekly for maintenance.

HOW TO: Add to the area with the most circulation.

PLEASE NOTE: Water temperature should be a minimum of 60°F (15°C). This product is very powerful and will quickly go to work consuming sludge. We recommend a higher water temperature to ensure that biological filter systems will be functioning and able to handle the extra bio-load. Keep out of reach of children. Store at room temperature.
