When Should You Clean a Pool Sand Filter?
A pool sand filter traps body and lotion oils, dust, pollen and other particles that fall into pool water. A filter should be cleaned more frequently if there is a heavy bather load, or if biguanide water sanitizers, such as Soft Swim or Baquacil, are used for pool water disinfection. The age of the sand can also lead to the need for more frequent cleaning. Filter pressure, the age of the sand and water conditions also affect when you should clean a pool sand filter.
