David Henderson Posted April 13, 2022 Report Share Posted April 13, 2022 Hi guys, Just moved to a new place and it has a saltwater pool. The pool is using AstralPool ZX cartridge filter and I was wondering if I need to clean the filter frequently to maintain? If yes, what should I do? Cheers, Dave Quote Link to comment Share on other sites More sharing options...
waterbear Posted April 15, 2022 Report Share Posted April 15, 2022 Clean the filter when you get a rise of 8-10 psi on high speed (if you have a variable or 2 speed pump). For example, if your initial PSI reading is 20 with a clean filter you don't have to clean the cart until it rises to 28-30 PSI. Quote Link to comment Share on other sites More sharing options...
