I have a 50/50 for my 14Gal biocube and love it. I run a 50/50 and an actenic. Everything seems to love it as well. It gives a little more blue apperance and everything green looks neon. If you do the upgrade I would run all three bulbs different (10,000k, 50/50 and actenic). Then you can simulate sunrise and sunset especially with the moonlights. Good luck!
