We bought a foreclosure house which came with the above filter and a 16 x 32 in ground vinly pool. I always had a 24' above ground pool with a DE filter. Had many issues with muck in the pool when ucovered a month ago. Finally had shock levels and chemistry under control but water did not seem to be getting any clearer. Bought new cartridges and within 2 days we saw a difference in clarity.
Let chlorine level drop and got slime in the filter and pressure climbed from 10PSI when clean to 20 to 30 psi. Got shock level back up but very difficult to clean between all the pleats. Taking the filter apart 3 times a day for cleaning with power washer or hose. Most of the slime is out but pressure starts at 10 to 12 psi after cleaning and within an hour is up around 20. When I take apart to clean around 28psi there is hardly any dirt coming out like when it was new last week.
Does anyone have suggestions on how to clean and maintain a cartridge filter?
