any tips on raising dKH & CA

[cbusreefer]

My tank has been holding steady at 350 CA and 9 - 10 dKH. I would like to get my CA up to around 400 and my dKH up to around 11, but I am having trouble. I dose Kent Marine CA one day, and super buffer the next.
Anyone have any tips on what I can do, or something that worked for them?

have you tested for your magnesium levels????

no, I have not yet. That is pretty much the only thing I don't test for. My tank holds steady where it's at. My whole problem is when try to raise... say dKH, CA falls and vice versa.

If Mg is low it is hard to get Ca and maintain it there.
