So I was in the pool store looking at solar covers complaining to the guy about how much I HATE solar covers (large pool, pain in the butt to get on an off, and makes the pool dirty) and he showed me a brand new product by Natural Chemistry called Cover Free. Said it is different than the solar fish, new technology blah blah blah. Has anybody heard of this? I know the general consensus on the board is that liquid solar covers dont work that well but I am wondering about this one. I have a heater and a 6ft privacy fence all around the pool. Wind is not that much of an issue. Not much wind generally gets through that fence. Also I dont run my pump at night. Only during the day. Not looking to heat the pool, just hoping to keep my heat in at night. Any thoughts?
