Like Mark posted above, read the article below (I read it several times before I first started dosing). I used his recipe of vodka, sugar (I got priming sugar from Beer Nut on State Stree for $0.78), and vinegar.
After reading a lot of forums and other articles, it was the article above that actually gave me the confidence to go for it. I dose 1ml per day in my 120G tank along with MB7. I also seed with Prodibio ever 6 - 8 weeks just to mix up the diversity. I occasionally miss a day here and there and have gone on a couple of 3 - 4 day vacations where the tank wasn't fed or dosed at all (except ALK and Ca from my doser) and everything was fine.
As Ryan mentioned, for the first month requires very diligent testing because the ALK and Ca demand drops drastically as your system adjusts, but then the demand greatly increases and growth takes off like nothing you've ever seen....water clears...color improves (if you have quality lighting)..and the fun begins. I am a believer that a quality skimmer is an important componant as it allows for export of dead bacteria..and it's the bacteria that consumes the nasties that we don't want in our tank (phosphates and nitrates). Meanwhile, the coral absolutely love to feed on the live bacteria and they will reward you for this.
