If you have a pool coming, you may need to do some above ground pool preparation. The most important step is making sure that the ground where your pool is going to be is level. If the ground is not perfectly level, the water in the pool will be higher on one side. If the level is a tiny bit off, then you may not notice, however, if it is way off, you will notice, and it won't be a pretty
