We recently purchased a used 21' legacy above ground pool... sort of like the intex.. with U shaped support bars. We had sand put down and my husband raked and smoothed the sand and basically eye-balled it thinking it was level... but once filled it was obvious just looking at the water level from side to side it was off... by about 6 inches. Even though he didn't want to, after my nagging about the possibility of someone getting hurt if it collapsed because the low side is only about 10 feet from a wooden privacy fence, he agreed to drain it and try to level it out. But how do we do that? He has put pavers under the low side but the problem is that every time you raise up a spot the bars in the next space come out and they have to be raised up as well to be able to lock them in place... and this just keeps happening all around the pool. Also on what was the low side where it is lifted up the bottom seam now goes up the wall several inches... wondering if this is a problem? And worried that it will make the laser level he's been using not correct. Is there an easy way to make sure it is level? He is already in the process of filling it back up and I know he's not going to be happy if we have to drain it again!! Please help!!
