I chose not to go T-5 or Power compacts with this tank since it is going to be non planted.
I LOVE the look of this type of lighting, but my other tanks from my old fishroom had T5 lighting, and the non planted tanks were a constant battle with algae.
I didn't want to go that route again so I did not choose T5 lighting for this one, even though you can get coralife T5 lighting that is very cost effetive, I would have probably needed 4-36" strips which I think would have been a constant battle with algae.
the T5's are very bright..
