Lighting Advice Please

I've got a 28 gallon bullet cardiff tank. Here is a link to my tank for reference. http://www.amazon.com/gp/product/B00...F8&me=&seller=

I have been in the hobby about 6 months now and am looking at upgrading my lighting. I've read *a lot* of the posts on here and in other places around the internet and the conclusion I've reached is that I really don't know what I need, but I have an idea. I've got it narrowed down to two lights I've seen discussed at length on this forum.

The two lights I'm deciding between are the Kessill Sky Blue LED and the Kessill Ocean Blue LED. Descriptions of both located at this link. http://www.marinedepot.com/Kessil_A1...FILDLP-vi.html

I want my tank to be able to support corals, clams, anemones, etc.... Basically I just want to have the flexibility to do what I want with the tank. Currently all I have is live rock and a few fish so I need to get a good light before going any further.

Can anyone please give me advice on which is better between the Sky Blue and the Ocean Blue (not the "Deep Ocean" blue) light? Or, if you think I need something else entirely besides these two choices I'd appreciate that input as well. My budget for this light is a max of $400 and it seems like I can pick up either of these aforementioned Kessill lights for about $265 ish.

Thanks for your time in advance.

 

Dims of tank? If you can go DIY, Razor would be a better option vs a Kessil...

 

My tank is 15 inches from front to back of tank. Tank is 20 inches deep with a 2 inch sand bed. From side to side its 20 inches across.

 

Also, regarding the DIY bit, I'll just be honest and say I'd rather just buy the ready-to-go stuff because I'm not good with putting stuff together.

 

You can get it put together if you buy from Stevesleds
