I just add more hose water after some evaporation occurs (on the rare days my water temperature is over 87 degrees). It seems to cool it down a bit for a day or two (do it at night!) but I know that’s not the most cost-effective or sustainable way to keep your pool cooler. I actually have the opposite issue. I want mine WARMER and I don’t have a heater or use a solar cover.I live in Georgia and our pool was at 92 degrees yesterday, it wasn't a very refreshing swim. What are some of the best ways to keep the water cool? We were thinking of getting a big sail shade to put over it.
Yea I think the humidity may be what is causing it to take a long time. I am not very patient so when it didn't cause a noticable difference after a cuple days I got frustrated. I will give it time to work like you said.The lower the relative humidity (not the lower air temperature) the more evaporation can take place.
