We are in the process of installing our 15 x 30 x 52 oval above ground pool. We have just put the wall up. We spent many hours trying to get it level and thought it was almost perfect... until we put the wall up and now we can tell that in some places it is off about an inch and one area is off by about 2 inches. When you look at the pool most of it is flush with the ground, but a few places you can see "daylight" coming from under the wall. Does anyone know the "correct" way for fix our problem? I know we could just put dirt under those areas, but won't it just wash away? Please Help!!
