Arch Chemical # Quart Winter Filter Flush

Arch Chemicals HTH 66508 1-Quart Winterizing Pool Closing Filter Flush

Filtration is an important part of swimming pool maintenance. Filtration, circulation and chemical treatment of the water are cornerstones to maximizing swimming pool performance and enjoyment. Clean, properly operating filters trap debris before they cause problems such as cloudiness and haze. Not all particulate matter is visible to the eye so even water that appears clean can contain matter that needs to be filtered out. Filters need to be cleaned regularly (at least monthly) during the swimming season. It is just as important to clean the filter before the pool is winterized, closed or taken out of operation. Using HTH Filter Flush at the end of the swimming season will help ensure a filter that can spring right into action when the pool is opened. Debris, algae or any matter that is allowed to stay in the filter for extended periods of time will effect the performance of the filter. The filter will lose filtering efficiency. Use HTH Filter Flush for sand, cartridge and DE filters of all types.
