Geez, I'm sorry it took forever to respond to this!!! To answer your question, I'm running a pair of RapidLED Onyx fixtures tied to a Bluefish controller to time / dim the lights accordingly. Lately I've been toying with the idea of adding a pair of t5 bulbs to aid in Acro coloration, but I'm not sure if I want to go messing with it. Colors are nice, you'll see in an upcoming post, but could be better. My desire to change things up is warring with my KISS gut feeling.Nova, your tank is beautiful! what kind of lights are you running?
