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!!

I would advise you to stop what you are doing right now. Your site is not flat and that must be corrected before you install the liner or water. No daylight allowed when installing a pool. Use a straight 2x4 to help you get the dirt level, dig down to level but do not add back any dirt. Once you are near perfect you can spread an inch of coarse sand and feather in with a rake.
