Low TA question

[jstblush]

I have been checking my FC everyday but not checking my pH as often because it had been running at 7.4-7.5 everytime I checked it. So today I finally did a TA test to see where it was at since the pH hasn't been rising. It came in at TA 50. I have not had to add any acid at all and love it because I hate messing with the stuff. So my question, is it a problem having a TA of 50 if it's keeping my pH between 7.4-7.5 constantly? The pool is inground vinyl if that matters.

As long as your pH is steady your TA is just fine. Each pool has its own "happy place" in regards to pH/TA ratios.

Ok, great! So no damage to the vinyl liner with low TA? If not this is great news because it is so nice to not have to add acid all the time.
