Given a vinyl, salt water pool:
I know if you have high TA, you may have a harder time maintaining PH. So the recommendation is to keep TA in the 40-60 range in order to control PH drift.
I guess I'm unclear what TA does in general. Why (again, in a vinyl, sw pool) would you worry about what level your TA is in general beyond just not wanting it to be above 60? Why is a TA lower than that a problem? Would going lower help even more in the PH drift? Or just cause unpredictable fluctuations in PH?
I know, I know, just keep it between the lines, lady. (I just like to understand how things work! )
