First slam last night. Even though I used the calculator, I got the fc much higher than I needed to slam. The fc at night was 30+. This morning, fc was still higher than I need in the slam, but my overnight fc loss was greater than 1.0. As I understand this forum, that means that I am not done slamming. Should I cover the pool with the solar cover to keep the chlorine high through the day today? And then re-slam tonight? I don't know why my initial fc got so high. I used calcium hypochlorite but will have to use liquid bleach tonight. WAter still is very clear, but not the crystAl clear you get when everything is going great. We had replaced over half the water this year due to high cya. Any help is always appreciated
