You are right, that amount of calcium is neglegible.
I noticed some calcium ascorbate products mention that it is 100% calcium ascorbate containing calcium carbonate. Seems to me that that is just a marketing gimick, it is either 100% calcium ascorbate dihydrate or it is less than a 100% and the rest is calcium carbonate filler.
Either case because the calcium carbonate does not dissolve at the tank PH of 8.0 to 8.4 that will be like adding a small amount of aragonite sand to your tank (like in purple up) and the real release is only the minuscle amount of Ca and of course the L-ascorbate which will be the same if you use ascorbic acid, magnesium ascorbate or calcium ascorbate.
In the case using ascorbic acid, instead of dissolving into calcium and L-ascorbate it dissolves into hydrogen ions and L-ascorbate (and some D-ascorbate) in this casethe H ions is what lowers the PH
So Calcium Ascorbate is *thumbs up* then?
