Hello there! Looks like a great forum. I am about to instal my second above ground pool. The first was put in pre-computer days and lived for almost 2 decades. It was a Sears good (as opposed to a Sears better or Sears best :P ) 24 foot with galvanized walls. It was installed inside of an old 65K gal livestock water storage tank on unlevel, cracked concrete with a sifted dirt cove, and eventually a tree root greater than one inch in diameter grew the whole way across the bottom, but I never had a leak except under the original wooden ladder step (and at the sun-damaged water line). It went through two liners before we had a freak storm/flood event in 2006. I have daydreamed about repairing the rusted wall and trying one more liner, but always seem to find higher priorities for the money. I just received this new pool as a gift.
New pool is an Intex 18 foot x 48 inch kit from wallyworld with cartridge filter and whatever pump comes in the box. It is small enough I think we will put it in the yard this time. I guess I am freaking out about the bottom and I am not sure why. What is the minumum you all would recommend? Not sure I want to bring sand in at this late date of the swim season, is the ground cover that came in the kit enough or should I add a few more layers of tarps? What about this gorilla cloth I see advertized? I found one for around $65 but not sure it is really needed. Yard is flat and mostly bare dirt, may need to pull a few bunches of Lehman's Lovegrass. Styrofoam? old blankets? carpet?
I know I will need to upgrade the pump/filter eventually but hoping it will do for now.
One additional thing I just had to ask about after reading a lot of the introductory stuff - on cleaning a swampy green pool - I didn't see any mention of using alum. I found that to be a great way to get the main pile of green out of a bad, late-August, forgot about the pool for a week and went on a road trip, ewwww yuck, should we just get frogs now? gross, thick, green "bloom."
