    21 ft pool...help me choose a pump sand filter combo.

    21 foot pool. Is 1hp 2 speed pump enough on half speed to just run and use the 1hp for cleaning ?
    Was looking at this heyward pump SP15922S (1HP 2 speed) or this SP15932S(1.5 HP 2 speed).
    to combine with one of thesethe S180T(18 inch) or the S210T (21 inch)
    If anyone can help Id appreciate it.

    I have that size of pool and that exact pump (1 hp 2 speed that is). Works great for me, I generally only run it on high when running my roof mounted solar panels or when I am running my vacuum (which I do not do often). Besides that, I run on the slower speed 24/7. The 1.5 hp is oversized in my opinion, so not a good idea for you pool.My filter is a 20 inch meteor which I think is rated for 45 gpm (I will have to look). For filter, definitely go with the 21 inch (at least over the 18 inch). Pentair makes a 3/4 hp 2 speed pump that I almost bought, and would have been a good fit for this size pool.

    a 1hp 2-speed is fine for your pool. You'll only have to run it on low except when vacuuming or backwashing. I'd opt for the largest filter I could afford.

    Great thanks guys. Does it matter if I only have a 1hp pump and say a 24" sand filter ? Will it be powerful enough ?

    Just echoing what Dman said. The 1 hp pump and a 24" filter is a good match.

    Thanks so much for the answers. I was looking at this filter...24" --there seems to be some wildy varied prices from 24" filter to filter...will this one get the job done ? Is there something cheaper that willl be equally effective ?

    The S244T is a great filter. Any of them in the 24-26" range that holds about 250#'s of sand will do.

    thanks I will order that on then from pool supply world. They are cheaper than amazon.
    I have the Wilbar Oyster Bay 21 AGP--steel with res caps. I did not get a skimmer with it...are all wide mouth skimmers the same size ?
    I was looking at this one...

    Pelican pools wanted 150.00 for a skimmer. Sounded like a rip so I passed

    It comes with a base. It doesn't come with the pump/filter combo base unless you order the combo.

    I have the S220T (22" 250lb) on a 24ft pool if you are looking to save a few bucks, is more than adequate for a 21' pool. As far as a base is concerned for my filter and pump, I just used a 36x36" PVC ac condenser pad found at your local hvac/plumbing supply store
