For those of you that have automatic pool covers, where do you put your water level in relation to the skimmer and/or the top of the tiled vault wall (where water spills over)? Did your automatic cover company have specific instructions like - a) keep it level with the tiled vault wall; b) midway between bottom and top of skimmer; c) 1" above the skimmer's mid-height; d) etc...? . I ask because the different techs that came to do maintenance and/or repairs seem to have different instructions/opinions. For the meantime, I have just been keeping it slightly above the skimmer's mid-height that puts it about 3/4" below the top of the tiled vault wall.
