I am in the process of building a 6ft tank at my house to be a mixed reef / fish tank. In my research journey I have decided that my largest expense is likely going to be lighting. I have seen many, many options but for me the jury is out on making a decision. Lighting this beast is going to be expensive! I am thinking about going some DIY route or buying something used. My tank is 25 inches deep so I need some decent penetration to get to the bottom of the tank. I am deferring to everyone here for their recommendations. If you were setting up a 6ft tank, and didn't want to spend $1000 for lighting, what would be your choice?
