I have a 23000 gallon pool. I am in south Florida and it is open year round. I have a pentair 520 cartridge filter with 4 giant cartridges. The pool is about 6 years old and I have replaced the cartridges once. I am finding that when things work the cartridge filter is fine. The problem is after a big storm or some other event that brings debris into the pool, the cartridges need to be cleaned. This would be fine if it were a once or twice a year thing, but it seems to be happening more frequently. It takes about 2 hours with the aquacomb to deal with that. If I get an algae bloom it could mean doing that multiple times in a short period while shocking.
I just had my pool deck pressure washed which brought a ton of dirt into the pool and now require me to open it up and clean those cartridges again. When I do, the pressure goes down to 4-6 psi when run at 40GPM.
I have been thinking about replacing this and going with DE as you can back wash the filter and would only have to break it down once a year. That would require a new multiport valve. I don't mind dealing with DE if it means I don't have to open that filter up.
I also have a suction side cleaner. I am thinking that I could get a new filter or I can get rid of the suction cleaner and go with an electric one. This way I am not putting dirt into the filter and maybe extend time between cleanings. Seems much easier to clean the pool robot than the giant cartridge filter.
It is also SWG so I know backwashing my require more salt and cya. Half the year I am finding I need to drain water anyway from the rains so I could use that time to backwash anyway.
I read all about the convenience of cartridge filters but it seems more work, especially when things go bad.
Is the new robotic cleaner a better investment or should I swap my filter?
