I am in N. Texas, where we are still having daily temps in the 90s. Pool temp is 80. I filled the pool up to the usual level on Monday morning, and by this evening (Friday), I had lost a little under 3" of water. I did the bucket test, and while both water levels fall, the water level of the pool seems to stay about 0.25" below the level inside of the bucket. Is it likely that this is a leak, or just evaporation due to the unusual high temps?
