Hi there i just got my self a 5.5 g and wanted to use it for my 1st sw tank. Now i dont plan on keeping any special corals maybe a few zoos, and shrooms and a gsp . I just want a few inverts and a fish(goby). I was planning a 10g but i just wanted to scale down and make it as portable as possible. Now i have noooo clue on what light to get. I dont want any expence metal halides just a pc florecent, and a decent fixture for it. Now what would be the apropriate wattage for a tank of this size? And where can i find a fixture that will use p.c florecents and be a good size for the 5.5g. Thanks for your help.
