I recently purchased an intex 20 x 48 Ultra Frame Pool - using the salt water generator & Sand filter - and using pool salt - we set it up this year on top of two tarps with a carpet cushioning and set it up. And got the water in it from the fishpond in our yard. My dad figured out how to filter it and got it cleared. Now the water is sparkling clean - and all of the chemicals are running properly. But come fall, the plans are to drain the pool and take it down. then borrowing the neighbor's tractor to move the dogwood tree - and dig a hole. In this hole, the hole will be dug in a square and a wooden box will be built inside the hole. then drainage lines will be placed and then pool will be set back up with the tarps and carpet cushioning underneath it. When it is all done, pool will be leveled with the back deck and will resemble a nice above ground pool. But for the summer, I plan to enjoy my wonderful warm pool. And by the way, try those heatkeeper balls from Walmart pool section - (ebay has these too) - they really do work!!!!
