I'm trying to lower my TA from 140 to about 80 so I can add borates.
I picked up some MA from the Home Depot while I was there for other stuff and its 14.5% MA. The lowest option in the poolcalc is the "15.7% -10Â° BaumĂ©".
What is the -xxÂ° BaumĂ© telling me? Do I just increase my dosage by ~8.3%?
Should I get a more concentrated MA from Leslie's or another PS?
