Earlier in the summer my TA was running around 80-100ppm and I needed to add about 2 cups of acid every 2-3 days to keep the pH within range (7.5-7.6 as a target).
I've only had to add acid on a regular basis the entire season, everything else was in line and really left alone.
Now as fall as arrived, my TA is at around 40-50ppm and I've noticed a drop in frequency of acid additions (expected).
The last full set of test results I performed:
pH = 7.5
TA = 40
CH = 400
CYA = 50
TC = 3
CC = 0
Are the additions of acid slowing dropping the TA over time?
I know it may not be great to have the TA that low, but what are the dangers in having it at this level?
