Ok, my water is clear and beautiful, I have passed an OCLT, but my water was green (but clear) at opening. and there was very little water. (opened may 12) but it cleared up with 5 gallons of chlorine and again I passed the OCLT. I also passed the CC at .5, but I've been testing CC regularly and it varies, sometimes it's .5, and sometimes it's 1. why?? it's driving me crazy. So, this week was COLD, so I brought it up to SLAM level and tested CC at .5 so I let the chlorine levels come down and now it's at normal levels and today it tested at 1.
