I recently learned that evaporation can happen at night as well from reading posts here. I thought I had another leak because the morning after the pump ran it seemed like the water level was low. I did a test yesterday where I brought the water up to a certain level, marked it and ran the pump during the day for the same amount of time that the pump runs overnight while I was home. the water level never changed the whole day.
The next morning, the water dropped some, so I'm guessing the overnight temps were cooler than the water which caused evaporation?
Anyway, my question is how do you all handle evaporation? are the pool levelers I see for sale online any good? or do I just monitor the level and add when necessary?
I want to make sure I don't get caught with the skimmer sucking air if I'm not home or come home later than usual.
