What is the optimal TA range for a liquid chlorinated vinyl liner pool? I see conflicting advice. I'm adjusting TA in prep for adding borates via boric acid.
So you want to add borates to your pool--Why and How says TA should be 70-80 ppm.
Pool School - Recommended Levels (and pool math) says 50-90+
Borates - Why and How says bring to low end of range for my pool which would be 50ppm.
I'm currently at 70ppm (down from 150ppm in May).
Do I really need to go down to 50ppm? If so, then why? I haven't had any trouble lowering TA, it's just time consuming. I've read that adding borates will reduce upward pressure on Ph allowing a lower than normal TA. Is that all there is to it?
Experts please weigh in. Thanks!
