Hi everyone. I am helping my inlaws with their fiberglass pool. It was a swamp and we have been slamming for a few weeks. We finally have the pool crystal clear, it's gorgeous. Last night the chlorine was brought up to shock level at 8:30pm and at approximately 2am it had drifted down from 15 to 12. Everyday I check cloromines and still seem to stay between 1.5 and 2. I don't see any dust or cloudiness and no algae. Is this just tail end of slamming? Thanks for your help.
