I have a purex triton fns plus fnsp 48. That side has cracked and I’m thinking about switching from de to cartridge. The pool is 13,500 gallons and It’s currently a salt water pool that I will be switching away from the saltwater as it’s indoors and things are starting to rust. Ie, the sliding doors. Being that it’s indoors it doesn’t get a lot debris in the pool. What filter should I replace it with? Thanks so much for any input.
Need new filter

Many of us have the Pentair Clean and Clear plus and really love them, mine has gone 7 years with no issues at all... I clean my CCP 320 once a year and not because the PSI raises 25%, it only goes up 1.5 PSI 14 psi to 15/15.5 psi at the end of year on my 15,000 gallon pool... I think it would work great for you

Also remember, a chlorine pool is a salt water pool... just adding liquid chlorine and muriatic acid and swimming adds salt.. Most pools have over 2000 ppm salt after 2 years... that is why we tell everyone to test there water when they switch to a SWG..
That’s a good point, never thought about the salt level of a non swg pool. Maybe I should start taking readings more often on my salt ppm and trying to keep it in the lower range
What kind of HVAC system do you have ? I’m guessing the humidity/moisture is what’s causing the rust, not the salt. Anything that isn’t designed to be around moisture, like the inside part of sliding doors for example, won’t fare well.
