Before installing an above ground pool, it is important to level the ground. This will ensure that the pool is stable and safe, and that the water is evenly distributed. There are a few different ways to level the ground, but the most effective way is to use a laser level. A laser level will project a horizontal line across the ground, which you can use to guide you as you level the ground.
To use a laser level, first set it up in the center of the area where you want to install the pool. Then, turn on the laser and adjust it so that the horizontal line is level. Once the laser is level, you can use a shovel or a rake to level the ground. Be sure to work slowly and carefully, and check the level of the ground frequently to make sure that it is level.
