This product is used to quickly settle unfilterable or suspended debris including algae that causes extreme cloudiness. It drops or "flocks" cloudiness to the bottom of the pool so that a layer of debris can be easily vacuumed to waste. This product can be used in all types of pools, will not affect pH, and is not corrosive. Do not use during a shock treatment. This product is most effective when used under normal sanitizing conditions.
Note: This product settles algae but does not kill algae. Be sure to resume sanitizing and/or shock treatment after vacumming is complete.
