Why oh why did I not discover this website YEARS ago! Season after season of battling pucks, powders, refills, and pool store products, I finally made the decision with the knowledge I gained here to take total control of my pool. How liberating and satisfying it is now to walk into the backyard and find this instead of a cloudy, almost clear pool! I am beginning to teach my father in law the lessons I learned here in order for him to manage his pool. Paying it forward I guess. Here's my family's modest little oasis in the hot south Louisiana summer. Thanks TFP and BBB
