I have been doing some reading on this and other various forums regarding carbon dosing and MB7 (MicroBacter 7 by Brightwell Aquatics). Is anyone on here using any such systems? If so, what are you using and what is your experience? I was thinking about running a LNS using MB7 and Reef BioFuel (also Brightwell Aquatics). I know some use vodka but that kind of freaks me out a bit. Rather keep the vodka to myslef!
