Here's my light hanger. I used a 5 foot piece of poplar and screwed it into 4 studs. I mounted some 1/2 inch steel rods to it. I don't have the lights yet but wanted to make sure I didn't have to do this over a full tank of water.
The plumbing is done too. You can't see it in the picture but there are unions on the pipes coming out of the bulkheads.
