Is it possible there is still something in the water absorbing my chlorine even when it has been completely clear the past few days? Just wondering if maybe there is a testing error on my part, either last night or this morning.
My pool is crystal, crystal clear (and has been since opening, just a tad cloudy when opening but nothing major - never green). We opened it Friday and noticed I had 0 CYA, and had some CCs. Added some stabilizer, and I have been SLAMing it since Friday night. It is getting much better (would lose chlorine immediately but now holding pretty stable), but it seems my OCLT this morning came out with still an FC loss of 2 ppm. (CCs were down to .5 yesterday - didn't bother checking them this morning since we already failed the FC portion). I couldn't believe it as I thought for sure we would pass the test this morning so we can give our filter a break tonight! I have never had to SLAM this long before, especially when the water is crystal.
There has been no swimming at all at this point. Brushing and vacuuming every day.
