I am using Oceanic right now and BL is right about the low ALK but I am not having any problems with Calc. I am dosing with bicarbonate regularly and am able to keep the ALK up to 2.5 or 3 but I am also dosing with 2 part Bi Ionic.
My tank is so new that it is using a lot of Calc because of the Coralline growth starting right now. The Calc was high in the first month but I attribute that to new Aragonite sand that is high in calcium and other minerals. When the Calc started dropping so did the ALK and now I have to pretty much daily take readings until I figure out average dosing quantities.
I here a lot of conflicting information about magnesium levels contributing to the problems of keeping the ALK Calc levels balanced, along with Ph of course. But that is for a different thread.
What is the skinny on changing horses in mid stream, so to speak. Would I have any problems switching to a different brand of salt?
