When in doubt about space for a new system... Go Vertical! :)

Figure 1 is what I came up with as a solution to my space and coral requirements conundrum. It's 2 33 gal long tanks and a 75 gal "sump". The 33's have dual VHO's (*only* because I'm out of breaker space.. 15 amp sucks) and the 75 has two 175w halides. The system is skimmerless. Initially, I had an SR 4 on the system, but it prevented getting the macro algae started. I removed it 3 months ago.

Figure 2 is a more close shot of the two 33's. I will be adding curtains to block some of the light.

Figure 3 is a more close shot of the 75. Reflectors have been added since, and I must say, they make sitting at the computer much more enjoyable.

Let's look more at the specifics of this system.

And no, I didn't take the picture of my neighbor's tank ;) That's how little room I have to work with.
