BioGuard PowerFloc 1qt:

BioGuard PowerFloc clears excessively cloudy water. This product is ideal for use after a rainstorm or a period of time when your pump wasn't running (perhaps during a vacation). The greater the amount of debris in the water, the faster it works. PowerFloc is very powerful flocculant. It settles suspended particles to the bottom for removal by vacuum and makes water clear and sparkling.
