Pool company didn't get back to me after he made an estimate (acceptable btw) and showed up and did the work. I am reading the manual but I have questions. Now that I have an SWG where do I keep my FC? I used to keep it 3-5, up it by 10 for shock or SLAM. I have an approx. 19k gallon pool got a 40k cell. And how much stabilizer do I need?
