2-3" in one day seems excessive at any time of year. I would suggest doing the bucket test for a few days and see if you do have a leak.

What is anyone's noted water loss rate in the southern/central US this time of year? I still wonder about the amount of water loss due to evap but could be because of the extreme dry conditions. Loss of 2-3 inches in a single 24-hour period and there is no sign of a leak anywhere I can "see". Doesn't mean there isn't one, but there don't seem to be the usual symptoms anywhere around the pool so far as I can tell.
