I am new to reef aquarium idea and am trying to set up a 75 gal tank. I have most of the equipment I need and am to the point now where I am considering buying substrate, live rock, and filling my tank. I have been looking at RO/DI systems to get my water as opposed to buying water to put in the tank for the long run cost savings. What other options are there for the initial fill of the tank?
Also I have been looking at the universal systems vs the value systems on bulk reef supply. I am assuming the universal system would be better but is it necessary?
