I thought I was the only one planning for colder weather in the heat of August. But I see someone is looking for a winter cover so I'll ask for advice on a solar cover. I have a solar heating system on the garage facing southwest and used a 12 mil cover last year and was able to get in the pool by February. Well, the dogs got into the cover over the summer and I am in the market for a new one. This time I thought I would see if someone has any recommendations on a solar cover. Some say black are better, some say clearer are better, how much does color and thickness for that matter effect heating and retention? Thanks for your help. I hope we can swim till November!
