So I am thinking about starting a frag tank and wanted to get some questions answered. specifically in regards to filtration and lighting. 1. filtration... do you need the same type of filtration as you would in a reef tank (refugium/skimmer/extensive water turnover)? I realize the water quality needs to be good but how does a frag tank differ from a reef tanks filtration? Would a HOB fuge with carbon and micro alge be sufficiant? What are the differences? 2. Lighting... If I were to use mh lighting (what I have on hand) with a low spectrum bulb I assume I will get the fastest growth..Correct? but will using a low spectrum bulb damage or physically take away from the frags colors. Do they need the high spectrum (10k/20k) to mantain their colors or is it just what our eye precieve. so it the frag was moved to a tank with T5's or 10/20k mh would they still have their color?
