LOL , thanks guys...I am using Mb7 right now but no form of carbon dosing..
so, the reason I am asking is that I have been told a couple different things:
1 - if the NO3 and PO4 are at or near 0 with just using Mb7 alone, then there is no need for a carbon source ( vodka, or Reef Biofuel, ect )...
2 - even if NO3 and PO4 are at 0 with just mb7, you should still dose a carbon source which aides in coral color, coral health, ect.....
Not sure which of those is the truth....any more info / advice?
If I do try to dose a carbon source, I will go very slowly and dose only a very small amount for several weeks before I up the dose...
