Okay, thanks. I saw that but wasn't sure if it was done automatically or not. The CSI reading I'm getting is -0.28 -0.32 My chlorine level is high at 19, trying to get that down. Turned the SWG down to 0 to see if that helps, salt -3200, pH is at 7.2, CYA -90, TA-110 I'm assuming the numbers are off from having the auto level off and having the water drop by about 4". Pool Math is mostly telling me to replace some of the water and add soda ash to bring the pH up.
