I'm in Tampa Bay area. My pool was refinished two summers ago - Diamond
Brite finish - so I am reasonably sure it's not leaking. But .... it
sure did go down fast this past week. I am keeping an eye on it but
really do think it's just evaporating. We haven't had any rain in over
two weeks. That system that has Ophelia stalled over NC has kept us
from getting any rain.

Think at this point, I would just keep an eye on your pool and add just
enough water to be sure the pump stays working. If mine gets too low,
it(the pump) makes a noise.
