So in SoCal we have been having a lot of rain. Tested pool today, FC is fine but I am getting low salt on my aqualink at 2200 ppm. Ph is 7.8, but the TA dropped to 40ppm. CH dropped to 425ppm from 600+ I assume from the rain. So my CSi is fine with TA @40 and ph @7.8 but is my TA too low? I was going to add some baking soda to raise it but thought I would check here first. My TA usually stays around 70-80ppm.
