FC = 14, pH 7.8 TA 160, CH 350, CYA 90, CSI 0.42
1. I'm tying to figure out if I need to try to adjust either the TA or the CYA. In the info about elevated TA there is a warning about simply hitting a target level. My pH doesn't seem to move very much and according to the pool calculator the CSI is 0.42 which does not seems problematic. Incidentally, my pool has two fountains for aeration.
2. I need help reading the Chlorine CYA chart. What does the Shock FC1 column mean?
3. I will happily convert to using liquid bleach and other household products to balance the pool. (I love this site.)
My only other concern is with the stains from Ike last fall and they are fading pretty well.
