    Sand filter and cartridge filter combo

    I'm putting in a new IG pool 18 X 47 Lazy L vinyl liner. Is it possible to put a cartridge filter in combo with a sand filter? Hope it isn't a bone head question, I searched but couldn't find the question discussed on any thread.

    Sorta' like wearing a belt with suspenders. Your time and trouble will be better spent just maintaining one large filter

    What's wrong with a belt and suspenders?

    On topic; one proper filter is sufficient.

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!
