It should work, carbon dosing is a fairly proven process.
The question is, does it work better than VSV? I'm sure it's more expensive than VSV.
So far? Who knows, I don't :p It is definitely a MUCH slower process.
In my opinion, carbon dosing is carbon dosing. People report different results with different methods. I have yet to see a monoculture/bacterial strands/cyano outbreak/film on the water/etc, dosing straight vodka, vinegar + sugar, or VSV in my own tank. In the tank with the Bio Pellets, no ill effects yet just dead bryopsis. These are the Warner Marine brand Justin carries if it helps.
