RE: Optimal Aquarium Depth and Fluorescent Lighting
If anyone replied directly to me, their reply went to an incorrect
address. The correct is associated with this message. Sorry for the
confusion. The continuing joys of a involuntary ISP change.

I know Vita-lites come in a 48" 110watt VHO bulb but are there a similar
24" VHO bulbs? If so, a source for them would be appreciated. If not,
it would seem I am pretty much stuck with Aquasuns. I really don't want
to go with MH. Any other suggestions?

I have a 90 gal. reef tank that is 25 1/2" in depth, so I am used to the
wet armpit syndrome. However, I was planning on a minimum 4-5"
substrate and, therefore, the situation should not be much different
than what I deal with at the present.
