Looking at your PM my recommendation is the following:
Your CSI is too far negative and should be closer to slightly negative of .0, for example "-.1" but doesn't need to be exact.
If you bring up the CH to 200 it'll bring you much closer which will be perfect and then when the PH will climb a little bit it'll improve the CSI yet again. The CYA can be raised too but will not have an affect on the CSI.
