Some advice please?

Asking what kind of filter is best is like asking who you think will win on American Idol!
For me it's a cartridge filter because I find it delivers the best compromise between filtration and ease of maintenance AND since I have a SWG it means my water balance stays more stable since there is no backwashing and dilution of the pool water. (My salt, CYA, and brorates, and CH stay stable and don't really decrease with time.) To me that is a MAJOR plus to a cartridge filter since it reduces my chem costs even more!

Edit: and if us Cart owners need even better filtration we can use either a chitosan based (natural) clarifier or a bit of cellulose filter aid (DE substitue) and get even better filtration! I have never needed either but it's nice to know the options are there.
