Janet,

I haven't looked at Intex stuff in a while, but mine had the pump and cartridge filter as a single unit. I suppose you could leave out the filter and run it as a pump and then attach a 100# sand filter to it. No need for anything bigger as the Intex pump (at least the one I had) was all of 1/6 hp. I finally chucked the filter a few weeks ago as we've been filling up 20 and 30 yard dumpsters over the last year So I can't even try it. We finally chucked the pool which had been in the shed for 8 years--because we had to pull down the shed, too.

(The demo team used 2 20-yarders, then we went through a 30 yarder, 3 20 yarders, and now are filling ANOTHER 30-yarder as the decks are being re-decked)
