I have the Jandy CL-580 Filter and want to buy replacement cartridges (so I can replace them when I clean the dirty ones). I see a 4 pack Pleatco PJAN145 brand for $169 at PoolSupply (includes $20 off) and $182 at amazon.
Is the Pleatco brand a good one? Any reason not to use a generic like Pleatco (as opposed to paying more for the Jandy brand)?
There is also a Cartridge called from pleatco PJAN145-M (antimicrobial) which is a lot more money $85/cartridge). Is that necessary or worth it?
