Hi and thanks for the good infos,

So I've pretty much decided on either the 2nd or 4th choice from the ones I posted above, I could probably even use only the 65w 10k bulb and leave the actnic bulb off (do you think a glass cover would reflect too much of the light?).

I'd like to check out the Odyssea you mentioned first though. I googled them but am not having much lucky finding a 24" one in that price range...can you link me a place you know of that would have that?

Also, I got to looking at Co2 injectors/systems. It looks like they are reasonably priced, $30 or so is what I'm seeing. One thing I see is they all seem to have to go in the tank? Do you know of any external Co2 systems (if they even make them)?

And just a side thought here...don't they make just a good old basic, cheap, not-too-wide strip light for compact flourescents that you can place one directly on both panes of a glass top and not have it go over the center plastic binding piece? Seems like that would be a simple thing to make, but I don't really see any of them around.
