We have a 45 x 20 pool, 36,000 gallons, and we are losing about 1/8"~1/4" of water a day. We have a cover on the pool when not used. The pump runs 24 hrs, and we have a salt conversion unit for chlorine, and a Polaris unit for the floor that runs periodically. Is this lose normal or do I need to worry? We have patch holes from time to time, but cannot find any at all now. Every summer we seem to see more lose as the year gets hotter and the ground gets dry.
