Lighting for a Chalice Tank?

I'm going to start up a 20 Gallong Long all chalice tank, What T5 fixture would 3Reef recommend for me ;D
I was looking at this one, Will this do?
Current USA Nova Extreme 2 Bulb T5 HO 10K/460nm Marine

 

I would go with a 4 bulb fixture so you can add bulbs that will pop all of the colors of your chalices. If you go this route buy 2 ATI blue plus, 1 ATI aquablue special and 1 UVL actinic white. They should cover all of the spetrum and give you plenty of PAR. Your light and flow should be medium levels according to what I have read for chalices.

 

my chalices are all at the bottom of my tank, and are doing pretty well. I agree on going 4-bulb though; you'll want to be able to use the extra sockets to make the corals pop with extra actinics (420nm).

 

Oh alright, Can you link me to a good fixture that is not the expensive?

 

BTW it's 30"

 

A 24" fixture will be fine. Coralife or even a fishneedit would work for the tank.

 

But it's a 20 Long, its doesn't matter? :-/

 

The more-shaded areas on the ends would be good for some chalices. There's a decent number that aren't high-light.

 

There usually aren't a lot of corals at the end so it should not be a problem. If you want wall to wall coral then a 36" is the way to go.

 

Yeah true but a 24" fixture would fit on top of the tank?
