I live in the Central Valley, CA. I had to drain/refill almost all my water because of extremely high CYA levels. My pool water also had really high TA, but normal levels of CH for a plaster pool. TA-350, CH-240. However, my tap water has high TA and low CH. I am still working the CYA levels down, but basically, my numbers will be:
CYA-90 and continuing to work it down to 50-60.
I am waiting to finish up the drain/refill for the CYA before adding my chlorine.
After reading other similar questions, I see that I should work on chlorine and PH first. Because I have to lower my TA and increase my CH, I was wondering the best way to tackle this. Because I am going to have to lower the PH and aerate to deal with the TA, should I tackle adding the required Calcium Chloride to raise the CH first? Can I do both at the same time or will adding acid interact with the calcium chloride for raising the CH? Thanks!
