Hello! So I'm starting up my Intex 3800 gal pool w/ SWCG this week. So far I've got:

TC: 2.5
PH: 7.4
TA: 170
CH: 100
CYA: 35

According to my hand little Taylor guide, TA seems pretty high and the calcium pretty low. If I add a bunch of muriatic acid to bring the TA down to, say, 100, how do I bring the pH back up to 7.4 without bringing TA up too? And if I add some calcium chloride to bring up the CH, what effect will that have on my pH?

This is my second year with this pool, and already I'm off to a better start than last year, but I've still got some stuff to learn for sure!
