Fill Water

We are on a well and the good news is the water softener is doing a fantastic job of taking the Calcium out of the water. The bad news is that the TA of the fill water is over 400. I wondered why my pH was staying at 7.5/7.6 but in the last couple weeks my TA has gone from 80 to 140 and I got it back down to 90. I had to add water as no rain has hit my pool in a while and WHAM there goes the TA.

Now knowing the TA is going to rise very time I add water, I'll have to add MA more often I guess...

Did your pH go funky with the higher TA? If it didn't, you might just be able to leave the TA alone. 140 isn't so bad. But I see you have a SWCG and that might make a difference. I know nothing about those chem balances.
