Good morning all. Have a quick question for the forum. I have a CYA level of 140 and I have been having to keep my FC levels relatively high. Ranging between 12-18 ppm. Initially I was keeping the chlorine around 18 ppm and in the last month started keeping it at 12 ppm. Each day I was having a loss of about 4-5 ppm. I havent had time to do a SLAM yet, due to work, but each day I just add enough chlorine to get me back up to 12 ppm. I have noticed over the last two days that I have started only losing about 2 ppm. My question is, would this indicate that whatever is eating my cholorine is going away? What would be your sugggestion going forward?
FC: average 12 ppm
CYA: 140 (will drain after the season is over)
