I woke up Saturday morning and checked the local Buy, Trade and Sell listing and a guy had a solar pool cover for sale. It hadn’t be used and I saved myself 1/2 off retail…$25. One day later, I can’t believe how much warmer the pool is. It says it’ll warm the pool 10 degrees celcius higher, and it’s having great effect 24 hours later. Come pool… warm up… I wanna go for a swim.
