I'm wrestling with how to light my tank. 6'x6'x2' footprint. I want to run 2 6' led fixtures but i don't know if I should run the 10,000k or the 6,500k fixture. What are some of you running on your tanks? Both fixtures are 8400 lumen, the 10k has the actinic lights. Which would make my fish look best and brighten the tank most? Not going to run the lights all the time. How do some of you show off your fish? Open to other options as well. Currently I'm running 2-4' shop lights with 8000k fluorescents.
