sodium ascorbate vitamine c by nutribiotic, i have heard a little bit about dosing reef systems with this stuff, and the amount to use and all the little do's and dont's. I just want to know if anyone has done it, or heard of doing it. Is it helpful or is it just a waste of time. I want as much info on the stuff as i can get before i go dumping a truckload of it into my tank (actually just a 1/4 tbs if caculations are correct)
