After dumping several tons of water due to salinity, and adding in new' I've almost got things back in balance.
CYA 70 ( or should be since it was 30 and I just added 128 ounces)
CH could use a bit more work. Salt could go a hair higher, but will wait for it to go down more from rain.
Went through several acid / aerate cycles to get TA down from 220 so that took several days. 1 gallon repeatedly dumped TA 40, so that was a good metric to learn for my pool.
Feeling like it's almost there.....
