Filter Cartridge Cleaning Instructions

 


General

Chlorine Users

  1. Remove the filter cartridge from the housing as per manufacturer’s instructions.
  2. Pressure wash with a garden hose with a straight flow nozzle.
  3. Allow the filter cartridge to dry to remove the fine particles.
  4. Remove the fine particles by gently dusting the filter.
  5. Algae, perspiration, suntan oil, and other oils present in filter can be removed by soaking the cartridge in a solution of commercially available filter cleaners.
  6. Excessive calcium carbonate or other mineral deposits on the filter can be removed by treating it with a muriatic acid solution.
  7. Rinse the cartridge clean and re-install it in the housing.

Baquacil Users

It is important to follow manufacturer’s guidelines and warnings when using Baquacil , Baqua Shock , and Baqua Clean.

Special precautions must be taken when cleaning filter cartridges used in a spa or swimming pool using Baquacil as a sanitizer. The filter cartridge must be cleaned more often and thoroughly when using Baquacil.

Chlorine oxidizes the bacteria in the water whereas active ingredient in Baquacil -- polyhexamethylene biqunaide (PHMB) destroys the bacterial cells. The active ingredient PHMB locates and binds to bacterial surfaces and attacks the outer bacterial wall. After penetrating the outer wall, the inner cell membrane is destroyed. This destruction allows the cell contents to disperse into their surroundings. They are further broken down into their elemental parts by non-chlorine oxidizer Baquacil Shock.

Baquacil is a mild coagulant which combines bacterial cells and other particles in the environment into particles large enough to be caught by the filter. The resulting deposit is a gray sticky film on media, which can only be removed with Baqua Clean.

If trisodium phosphate (TSP) or any TSP cleaner is used prior to stripping the film, the cleaner and the gray film will combine to form a gum-like substance. Once this occurs, the substance cannot be removed from the media and the filter cartridge must be replaced.
