I have the following above ground pool : Coleman 18' x 9' x 48" Power Steel Rectangular Frame Above-Ground Swimming Pool:
- Water capacity (90 percent): 14,812 L (3,913 gal) This is a Walmart product, used it last year and was very disappointed in it's filter and vacume options. I would like to purchase a sand filter, a skimmer, and vacuum for this pool, however when reading options from Intex on eBay, amazon and other sites many people say they cannot find adapters at a reasonable cost, I just saw a very unique skimmer at a pool company nearby that comes with the quick swim pool that comes from spasharoundpools.com it just hangs over the edge and attaches to the intake valve?? I was wondering if anyone here as any suggestions on a brand and type of sand filter that comes with connections that will fit my coleman pool? would like to have the option to suction vacuum if possible.
for visibility. Your situation is a bit challenging (to me anyways), not because of the conversion sizes from Coleman to Intex. Actually, many of their parts are supposed to be interchangeable. Anything that's not you should be able to get at your local hardware store. But your pool volume is barely over the 3K seasonable pool size that many folks simply maintain, dump and refill. What that means is that you have to evaluate whether it is cost efficient to invest in an upgraded pump/filter for that size pool ($150+). It will be interesting to see what others have to say since some of our readers break-down pump/filter size to pool ratio very well - it's what they do.
