Have some cloudy water at deep end. Test results are Cl 5.0 and 0 cc.=5.0 TC, TA 90 since rain during night, pH 7.8 and CYA 50. Not sure if I have the start of a problem or not based solely on somewhat cloudy at the deepend. Also I just increased cya from 30 to 40 a few days ago, but showing 50 now.
