adding acid

History of my interest in this question: I found that after 6 months my salt cell was full of calcium deposits. After cleaning it I measured the Total Alkalinity (using TF-100) and found it to be 180 Over the course of 3 weeks I added acid daily to keep pH at 7.2 until the TA was down to 70...

Due to illness, the belated startup of my pool happened last week where for the saturation index (at the current 69 degrees Fahrenheit & 7.6 pH), I need roughly around 3 full HASA cases of 31.45% muriatic acid (to drop alkalinity from 270 ppm to 100 ppm) and just under about 50 pounds of...
