Hello, you guys helped me clean up a foreclosure SWAMP a couple of years ago. Now I'm slamming my own pool b/c the nasty cover was dumped in the pool It's been 1 week & it's coming along. BUT for some reason there's a green tint on the liner? Water is clear, the only place there is no green tint is the very middle? Will this go away when I'm finished slamming? We're about to put our house up for sale & need it looking it's best. Thanks!
