Steve Weast's Aquarium

Note to viewers: Notice only the front panel of the aquarium itself is viewable in the living quarters of the home. The entire set-up is in a separate, adjacent "two-story room" and that the lighting equipment can be slid out of the way for servicing the interior portion of the aquarium.
