I am a new pool owner (first season) and I will be closing my pool along with the help of a friend who has experience closing his own. My question is if I lower the water level to approximately 4" below the return lines it would put the water level right in the middle of my lights. I have 2 lights, 1 in the shallow end and 1 in the deep end. I also have a mesh safety cover and this spring the water level was quite high. I am not sure how my lights come out either. Should I be lowering the level below the lights?
