Thank you. That's what I started with using borax but I started to question myself. We are draining and adding water a little at a time to decrease the cya and my fill water always has a lower ph. Using these methods is new to me and I and questioning the way I have always done things.
Yes, definitely PH first. Soda ash will raise PH and TA. Borax raises PH with not much TA increase.
