    New Intex Pool With Sand Filter

    Great forum here, thank you.

    We just purchased an 18' x 9' x 52" Rectangular Ultra Frame Pool (w/ 1,200 gph Sand Filter Pump (w/ 1,200 gph Sand Filter Pump). This is my first pool with a sand filter. That said, when using a sand filter are the chemical measurements (pH, chlorine, etc) performed in the same manner?

    I should add that as far as the included pump goes I cannot see this being sufficient for a pool holding just South of 5,000 gallons of water. I can supplement this with a 40GPM pump with conventional filter.

    I just spoke with their T/S and frankly could not understand her accent, let alone with each question "Hold on please" when she was apparently relaying my question to someone else. In any event I believe she said I need to purchase 'Sili Sand'? How often need this be changed?

    ANY
    guidance or bits of wisdom would be greatly appreciated and thank you!

    Welcome to TFP!!!

    Yes, the testing is the same regardless of the type of filter.

    You need to use #20 pool sand.

    Best pieces of advice:
    - Avoid the pool store
    - Invest in one of the Recommended Test Kits
    - Stick around TFP reading and learning

    EDIT: OH!!! And make sure your LEVEL the ground before putting up the pool. The supports should all be within 1" of each other. Always dig down and do not backfill to raise low spots.

    She was probably saying "silica" sand. As jblizzle stated, #20 pool sand is what you want. You can get it almost anywhere, including most hardware and big box stores, in addition to any pool store. But avoid the Qwikrete brand.



    Sand doesn't really ever need to be changed. It's already millions of years old. But you may eventually need to deep clean your filter after a few years. Search the forums here for how to do that. I've never needed to do it personally.

    Why avoid quickrete brand if you don't mind my asking? Just bought a new sand filter I'm going to install when these Florida rains clear, and bought quickrete sand from Home Depot.

    Thanks

    My findings on how not all sand is created equal should explain why.

    To be fair, that thread was likely a fairly isolated event and one would hope that the issue has been resolved by Qwikcrete ... although who knows

    Thanks guys, I'm going to open up the bag tomorrow and take a peek at how it looks inside. That thread was helpful. Excited to install the new filter hopefully this weekend.

    Hi,

    The good news is that we're setting up the pool tomorrow and the bad news is that neither Walmart, Home Depot or Lowes have Silica Sand in stock....looking at least a week delivery. Play sand is plentiful though but is this a viable solution, even if only temporary?

    Thank you!

    No, it's not. Wrong sized particles that will probably slip through the laterals. You might just have to hold your nose and visit a pool store.

    How true. They symbol for these pool stores should be a large jar of Vaseline.

    I did find pool sand at Leslie's, Lighthouse stock #9919, fifty pounds. What threw me though is that she said it was "Number 50" and I asked if she was referring to the fifty pound bag. She said no, it was Number 50. I thought I needed 'Number 20'. Any thoughts on this?

    Again, thanks for your help!

    I'd be wary of that sand.

    #20 shows .85mm
    #50 shows .30mm

    Does the bag say pool filter sand? I'd believe the packaging more than a clerk at Leslies.

    Yes, it does say pool sand but not grade is to be found on the bag.

    Do the grains look consistent sized? It's a good sign that they're not ashamed to let you see the product before you buy.

    It's probably #20 and the clerk at leslies didn't know what she was talking about.

    Thanks. The grains are consistent and I'm sure you're right. So far so good and thanks again for all your help. I cannot recommend this forum enough!
