is this enough light for a 20g regular tank?

is this enough light for a 20g tank?

Looking to setup my 20g for a frag tank. Basically after I'm done fragging, I'll be keeping zoa frags in this tank. Will this T5 light setup good enough? Not looking for growth, but enough for the frags to stay healthy until bought and shipped. Here are the specs of the t5 fixture, and remember its going on my 20g tall tank. Thanks in advance.

What are the tank dimensions of a 20 regular? 18 deep? What type of frags are you talking about and how long are they going to be staying in the tank until shipped? Also, are you going to keep them high on a frag rack or low on the bottom. I think they should be ok but it's better to hear from some of the experts.

Most any zoanthids would be fine in that tank with the 76w of lighting mentioned above. The softer 36w setup would probably be okay, especially if the frags were on an elevated rack. IMHO, I would go with the brightest light I could get on there (within reason, obviously)... as its always easier to dim the lighting (shading, for instance) than it is to get more light output from a barely adequate (at best) setup. Who knows, you may even decide to use that light at some later date for other more demanding corals...
Hope that helps some...

I've kept sps in this same tank with regular t5 lights, so I'm sure the later light fixture would keep zoas. But as the other said, I'd go with the higher light fixture as its easier to tone down then upgrade.

thank you all, here are the dimensions on my tank, 24″ wide X 12″ deep X 16″ high. I'm basically going to frag my zoa colonies, then place it in this 20g tall tank until someone buys them. Hope the dimensions will help out a bit. Thanks again, here is a similar pic of the type of 20g tank I have, oh I'll be putting the zoa frags on, the bottom and on the shelves i'll be making for the tank.
