Bryan;

Actually I was considering the Current Satellite Dual fixture, so I'd
have the same amount of light. I've heard that the fan in this fixture
is pretty noisy, though.

I just got this one. May be more light than you want but it has everything
you need. It has glass between the bulbs and the aquarium that may keep the
corrosion from the fixtures. Take a look and let me know what you think. I
was looking at Aqualite's originally but went with this one.
