How to hang the lights?

[MuralReef]

So I have an Aquamedic 3 lamp MH fixture and it is heavy. I can't figure out how to hang this over the 180 that will be going in the library. The ceilings are very high so I can't mount it to the ceiling. I looked at Walter Whites build and the hoist he built is really cool but again what would I fix it to. Plus I want a canopy of sorts so the kids don't look directly at the lights. Any thoughts or ideas would be great and keep in mind I want a clean look since this will be in a public place.

Plus I have 2 LED strips to supplement the MH that I plan to use as well.

I was thinking about using aluminum angle pieces to make the frame.

That's what I'm gona use to mount some new radions I have.

Thinking I might customize some legs.

I was going to suggest that. If you really want to get fancy, make an aluminum frame around the top of the tank that you could hang an adjustable height setup from. You could frame that with wood (held on with strong magnets for easy access). This is very clear in my head, but probably not coming through very clearly in my description :/
