So I realized that I ran out of Triton Core7 3B this morning, and upon searching, can't find the refill carton that I thought I had. I ordered the 5L Jugs a few days ago but they will not arrive until the 19th. I looked around and it lists 3B as Alkalinity + Trace, which is the same as 3a, but i'm assuming that is a mixture of different trace elements than 3b. I do have a container of the original base elements (the one that isn't core7) that was mistakenly sent to me around a year and a half ago, however I've previously been told that it isn't the same mixture. Is this something I can use to substitute until the refill jugs arrive? There is still a little 3b left in the dosing line, I doubt it will last more than a day though. Anyone got better ideas?
