Here in Miami I mentioned to my brother that I have to refill my pool quite frequently. My pool receives direct sun from 11am or so till 3pm. He tells me that he doesn't fill it that often and the level remains constant; his pool receives direct sun all day.
I dont have measurements of the water level but will collect them once the pool is done filling up today. At present I'm simply going by comparison to what he tells me, and I don't have any cracks along any walls or the floor.
Aside from leaks from the buried pvc pipes that I cant see, can water be leaking from somewhere else? I will update this post with a measurement of water loss in a few days.
