After reading a post here on TFP, on how much better the Intex (gray) Ultra Frame is compared to the Intex (blue) Metal Frame, I'm very interested in possibly taking that route to my new AG pool. I watched the YouTube video on setting up the Ultra Frame pool and I see there is a through-the-wall skimmer attached to the filter cartridge, with the pump hanging below -- all of which is suspended on the side of the Ultra Frame - not sitting on the ground below. I also read, here, that the pump and filter on the Ultra Frame are still the same old poor quality as in all the Intex packages. So, how does one replace this side attached filter and pump with one, like a Hayward System, on the ground?
