As of today tests,
So with that I have a few questions. I am in the process of lowering my TA. I added muriatic acid to drop PH and will then aerate with swg and deck jets. I added cya to raise that. I used pool calculator to figure out dosage. My questions are my auto pilot digital says salt level is 3400 but my testing gives me 2800. Why is my swg so far off. And should I add salt. Also should I try to lower my calcium or just let it ride. I have a vinyl pool. Thank you for your input.
