I have maintained my FC at shock level and passed the overnight test last night. My CC was still at 1. The FC has fallen down to 18 from my shock level of 24, but it now passes the CC test at .5. I have added another gallon of bleach to return it to 24. My question is does it have to pass the CC test at the shock level or should I consider the SLAM complete as of now? I have crystal clear water. Also, one follow on question - how far down does the chlorine have to come for it to be safe for swimming? Thanks!
