New pool (to us) this year. Has been up since mid May. Kids have been in it since even though it was too cold for me. Water temp was around 70 on average. So I had been looking for a good price for a solar cover but just didn't follow through. Now for the last couple of weeks, water temp has been 85 and been a steady 95 deg for the last few days. Now I wish there was a way to COOL the water LOL
