I went on vacation for a couple of weeks and a friend agreed to test the pool and balance (especially acid since we have a salt pool). I got back and tested the water at PH 8. I added acid and balanced. Went swimming three days later and found snow flakes in the pool.

Current reading
FC 4
TA 80
PH 7.4
CA 525 (i know we have well water at 375)
CYA 75
Salt 3500
pool temp 86

Will the flakes go away and is there any major damage that has been done?

If they let the pH get up while you were away it could be the reason for the scaling. If you keep the pH down on the low end it'll probably redissolve.

As stated in a previous post i went away from a couple week and a friend forgot to put much acid in the pool. I got some snow flakes in the pool. I then reduced my PH and am holding at 7.2-7.3. The flakes continue.

chlorine- 5.0
PH- 7.2
CA- 725 (its high)
TA- 60
CYA- 75


Even with the high CA it should be balanced. Do I need to do a drain and refill to lower the Calcium.

You have a negative CSI even with a CH of 725. I suspect you're dissolving some scale. What does your swcg cell look like?

It has some build up every couple weeks that I clean off, but not much. advice?

If you keep CSI more negative, calcium won't build up on the cell plates so much and you will stop getting calcium flakes in the pool. Depending on why your CH level is so high, and how practical it is to do something to lower it, there may or may not be a practical way to make that happen.
