Hey All, I am on the verge of setting up my first reef tank - very exciting times. It will be a mixed reef in a 120g acrylic tank (4x2x2) with a side over flow. The last major purchases I need to make is the lighting and controller. I am trying to decide between a powermodule (8x54W 48") or 2 free floating 250W MH (perhaps ushio, pheonix, or radium on a bluewave7 ballast) or maybe I just go LED! I live in Santa Cruz so it is not usually very hot in the summer. Would I need a chiller on my tank under the 2 metal halides if I put the pendants 10-12" above the water? Any thoughts? Any lighting recommendations? Thanks in advance!
