I been dosing my 100 reef for about three or four months now, only start on a well cycled tank.I have seen a change when I am dosing my skimmer goes into over drive pulling waste out of the water column.got to start with a low dose here is where I got my info on it there is alot of info on that subject. http//:reefkeeping.com/issue/2008-08/nftt/index/ptp
I just went to a medical supply store and got a IV line shortend upto what I need, set the drip for as slow as I can get it old syringe with no plunger mount it to the door so every mornin when I get home I dose the tank.I am at 20ml and thats my maint dose so read up on it, I havent done the suger,to me its easier touse vodka than dissolving the suger up. a bottle lasts me about 6 weeks, sonot bad for an $8 dollar bottle, if the web address doesnt work just got to reefkeeping.com and search for vodka dosing. good luck
