Good luck!
This is a salt pool so having the CYA higher WILL lead to better pH stability because there will be less ougassing of CO2 because of less cell on time. 30 ppm is too low for a salt pool.

Also, dropping the ALK to 70 ppm will also help. However, it will get there on it's own fairly soon if you keep the pH at 7.2 for a while to dissolve the scale deposits.
