Outlawboss is right about the actinic lights. As a former reef-keeper myself, I had an addiction to the beautiful hues that only true actinic lighting could produce. I found that going with a mid-low light setup, I was able to supplement some actinic for aesthetic purposes without any bad reactions (no algea problems, normal plant growth continued, and fish appearance intensified!).
If you are looking for more of a high-tech, high-light design, I'd steer clear of the actinics altogether.
I have that same cube (24 gallon ver.) and I love it! It's a low maintanence fern & moss setup that houses a lone puffer. I kept the stock filter and lighting and it's doing fine.
