Was out of town last week and with the storms of Texas I returned to a dark green pool again.... I measured my chemicals and here are the results
Chlorine 0, CH 200, CA 0, TA 100 and pH 8.0.
I have the acid to lower the pH but wanted to know if I need to raise my CYA from 0 before I start slamming. I looked at the Chlorine/CYA chart to figure out my shock level and the instructions read the lower the CYA the lower chlorine level needed bring to shock. The chart starts at CYA 20 shock level 10 but doesn't advise what to do if CYA is less than 20 or 0.
Thanks
