Seems like a strange thing to do. Which bottle would the formate be in? The alk or calcium bottle. I guess it explains why pro is higher concentration than most other two part systems. It only takes 7ml to raise 100l 1dkh as opposed to 10ml for plus.
Yes, It is in the alk part to push the alk concentration higher than can be done with the carbonate:bicarbonate alone.
