I live in an area that freezes and must winterize my pool. I've followed the BBB method all summer with great results! After researching winterizing, I have a question about chemicals - one place I read said to bring it to SLAM level and close and the other place I read said to bring it to SLAM levels 3 days before and make sure it holds and then let it drift back down to normal before the close. Which should I do?
Thanks so much!!
