black light?

[jbird69]

This is probably a lame question but I saw a 22" flouescent, black light fixture at the local supermarket. Of coarse whenever I see something cool like this I immediately think of my reef tank:mixed: Has anyone tried one of these for a night light or a supliment in addition to standard lighting?

I turn my black light on the tank on a few nights a month, its cool to see the green fluorescent pigment in the corals and all the coraline algea get bright red, Im not sure if it will have any ill affects of running them all night.
