I have found a neat little 25 gallon cube tank I would like to purchase and start a build with. My first question is, with a tank that size, what would some of you recommend as far as lighting goes? Second, how would set up the filtration system? Would you build a sump with a skimmer inside, or go with a more generic type hang on the back of the glass filter? Also what size of a power head would be effective enough in a tank like this? And lastly, any advice on aquascaping to maximize the surface area of my live rock so I can add lots of colorful corals would be appreciated.
