i'm looking thru PentAir cartridge filter selection on their website and there is no clear explanation of the difference between different model lines.
It seems that Clean & Clear Filters might be for AGP, but i'm not sure if that's the case. Is C&C Plus for IGP? How about C&C RP? There is also Posi-Clear, system 2 and system 3.
Can someone give me a quick rundown on the model line?
