Lighting for QT tank

[lancer99]

I'm in the process of setting up a 20G long (30 x 12 x 12) QT tank, and don't know what to do about the lighting.

 

I've read that a QT tank doesn't need as much light as a "normal" tank, but it seems like it would make sense to do light acclimation there (since any corals will be there for at least a month) rather than in my main tanks, which are all MH & VHO, all about 6-7 wpg.

 

It's in the bottom of a stand, so the fixture can't be any longer than 30", and I have about 7-1/2" of headroom above the tank.

 

And I'd like it to be adjustable so I can do the light acclimation.

 

Suggestions?

 

Thanks,

I'm assuming then that it's QT for corals since you said light acclimation. In that case, I would use the same lighting, or close to, what you have on your tank. You won't need as much since the depth of the coral in the water will be much less so you don't want to burn it, but you also don't want to have to completely reacclimate it to your main system if you can avoid it at all.
