I guess I'm missing something here. I understand the Ca/Alk/Mg as most of us already are use to that part. But Macan spreaker event, talked about V gets used by tunicates, silicate sponges, iron based on algae and corals, Barium consumed higher with Montipora, Manganese for Goniopora. All of these variables which is the whole reason for testing. So I don't see how you can do a single one size fits all Trace Elements "ut they also contain trace elements in proper ratios in the 3rd part." unless this is custom tailored for us based on our test results.
So I would assume your selling the individual trace supplements as well such a V, Mo, Mn, Ba etc ?
