metal hide

        Well i was suggested using a 100 watt mh bulb for my 29 gallon
tank.  Off hand it sounds like a it is a bit powerfull but I'm open to
the possibility.  Question is are there hoods or lights readily available
in metal hide or is it a custom build it your self project.  Also what
about something like 75 watts?  And what do these cost?  And where do you
get them from?  The local aquarium stores do not carry them and act dumb
when I ask about them.
