Ok, so I have a 3 foot reef (see pic below) and I still use VHOs. I've been given the green light by the wife to upgrade to a 6 foot tank. Only problem is I have a surplus of 36" VHO bulbs and would really like to use them up in the new tank. So I was thinking about mounting my 36" VHOs on one side and putting a single Metal Halide on the other. 1/2 the reef would remain unchanged with softies/LPS, but I could build a separate reef on the Metal Halide side to grow SPS. Thoughts? Suggestions? Will this just look stupid or something?
