I bought a 75, got an overflow and wet/dry, and put a Metal Halide over it for my first reef tank. The tank cost me $5 at a thrift store.I am thinking of buying a used tank to then turn into a reef tank. Once I find one I will buy it, and do whatever I need to turn it into a reef tank. I would probably plumb it and have a sump because I would want it to be much larger than my nano. I think it would be a fun project to do in my free time. What do you all think?
