Yes, the apartment manager made some calls and said weight was no problem. They did suggest renter's insurance in case I damaged the walls or floor with spilled water or with spray from the tank.

Quick question about open top tanks. Electricity and salt water are not a good combination. I see the T5 lights have mounting brackets that attach to the side rims of the tank. It seems to me salt spray, or worse, if I bump the light, it may go in the tank, short, electrocute me etc. How do I prevent that without a glass top?

Wow, I guess things have changed since I was in an apartment(>10yrs). Cool for you!

If you run a canopy, just retrofit T5's into it. If you run a fixture, you can hang most of them or place on the top. Most(all?) have some type of splash shield to protect the reflectors and electrics. My TX5 has mounting tabs on it that keep it mostly stable on the rim. I can move it back/forth without really worrying about dropping it. I have to take it off to do any real work though. Also, see about swapping to receptacle with a GFCI unit.
