I am wanting to buy a pool cover for winter, I live in southeast. I have no idea what kind to get or what is the best style. I have a 16x32 rectangular inground vinyl pool. I dont know if I need one to just keep out debris or if I should opt for a solid cover (like aqua master) which looks to be about $700 from what i can tell. I dont wanna spend a fortune but at the same time I don't wanna half *** this. Any help would be greatly appreicated.
