According to pool math, I needed to raise my CH and TA levels. I bought calcium chloride and baking soda to do so. I do not own a scale for the powders so instead I bought amounts that were around double what I needed. I marked the level on the outside of the container then split it in half and marked that amount as well. I then added until the level was to my half mark.
I let everything circulate for roughly 1 hour and remeasured. Both CH and TA did raise, but went above what I was targeting. I wanted to raise CH from 250-300 and TA from 50-90. I instead ended up at CH of 350 and TA of 120, measured twice to confirm. All of my other levels are good (FC 5, PH 7.5, CYA 45-50) and the water is clear. The pool is gunite. Do I need to be concerned with elevated CH and TA levels? With these values pool math has my CSI high at 0.5 and another source has my LSI at 0.6. I am not too familiar with how CSI/LSI correlate.
