I too am going to be getting a tank from this website! I am either going for the 6 gallon with 54 watts pc lighting (one of each 50/50, actinic and 10k) or else I'm going to get the viper metal halides. I'm a little worried about halides though, maybe over heating or just being difficult to keep mh's at college! Plus, on 6 gallons, I think 54 watts of pc will be wonderful and I likely won't need too much more to keep most things. What do you guys think? I am extremely glad to hear good things about the company too. I called them a few weeks ago, and they are extremely helpful!Hopefully my cube won't crack! That is the first mention of that problem that I have heard though.
