This is my second year with a pool. I have an 18 X 36 19,000 gallon inground pool. I Live in Western Kentucky where it is very hot and the humidity is high. I am experiencing what seems to be a lot of water loss. Maybe 1" to 2" per week. I dont remember having this issue last year, but I cut down several trees last fall so the pool sees a lot more sunlight. The pool has seen more action this year as well. Could this be an evaporation and splash out issue or do I have a leak? What is normal water loss due to evaporation?
