Thread: A few questions about sand filters

    A few questions about sand filters

    I have a 9k gallon inground, 3/4 hp Super Pump, 1.5 " piping.

    *People have recommended that I get a Pentair Sand Dollar filter, but all of them that I've seen say they are for above ground pools. Will it work for my inground?
    *If they would work, what size Pentair Sand Dollar filter do I need?
    *I've also been recommended the Hayward S220T. Anyone prefer one over the other and why?
    *Any other suggestions besides the Hayward or Sand Dollar that would fit my setup?

    Thanks!

    Re: A few questions about sand filters

    The Sand Dollar filter is just fine with an in-ground pool. I recommend getting the largest one you can afford and have space for. The Hayward S2XX series is also fine.

    Are you set on getting a sand filter? Or might you be interested in a cartridge or DE filter.

    I have the S220T and would think that would be a nice fit and well oversized (a good thing) for your pool.

    Oh, not 100% set, it's just what I'm used to and I thought this would be the cheapest way to go. Should I be interested in cartridge or DE instead?

    If I thought I could do cartridge or DE for the same or similar price, I would. I haven't checked pricing, but was under the impression that those options would be much more costly.
