I have been using Randy’s formula #1 for alk (soda ash) and BRS (Randys formula #1) for calcium. I calculated that when I am dosing equal parts it should be a 1:1:2 calcium:alk: part c; however, when dosing unequal parts of alk and calcium and/or correcting alk vs calcium, how do I determine how much tropic Marin balling part C to add?
Example: dosing 85 mL calcium to raise 83 gallons 10 ppm, dosing 41.5 mL soda ash to correct alk from 7.3 to 8 (not all at once).
