Very interesting design. And thanks for the excellent article.
I also built my own hood, but my hood was much simpler. The top
is one solid piece, hinged at the back. Much easier to construct.
One thing though: I also have my ballasts in the cabinet under
the tank, with six-foot cords between the ballasts and the bulbs.
However, I do not need any grounded surface anywhere near the
lights. I am using T10 and T12 bulbs, with electronic ballasts
(Magnetek and Coralife Wizard). So is the grounding requirement
only true for some types of ballast/light?
