A couple months back I had calcium snowflakes pooling the in bottom of the pool. CH was 650ish and TA was 110. I got the TA down to 65. The snowflakes have stopped but I do have floating scale on the surface. I assume that is calcium.
So I went to a mom and pop pool store I buy acid from and he said my TA is too low and should come up with the high CH when I mentioned the little floaters I had.
To keep the calcium from scaling and creating snow in the water, I want low PH and be on the low side of TA range and keep my CSI at 0 or neg, right?

To help prevent the accumulation of scale to begin with, yes, you want a slightly negative CSI. If the CH is beginning to get too high, especially in the summer with higher water temps, you compensate by closely managing the pH & TA to keep them a little lower. Getting the TA down to about 60 is perfectly fine. The mom & pops store is probably just referencing generic industry levels of 80 - 120 which is not a good thing to do.
