I am not sure where you actually have the water level but I take mine down below the skimmer and return lines. This is about 18" from the pool deck which is what is recommended by the mesh cover manufacturer (loop loc). I leave it there and by early spring I have to lower it again to a little below swimming level and then by opening it's up to or above swimming level.
