9325k versus 50/50

[105man]

I just bought a compact fluorescent fixture. It came with a 55 watt GE 9325k bulb, and I also bought a 55 watt 50/50 (10000k and Actinic blue) Coralife bulb.

There's obviously a difference in appearance, but is there any nutritional/health difference?

Also, would you keep the light on about 12 hours per day, like a regular bulb?

Live rock, live sand, fish (tang, flame angel, basslets), shrimp, algae critters, soft corals (mushrooms, polyps, leathers, dusters).

Thanks!

which one do you like better?

the 50/50 may give you more in the UV range so the softies may get more energy for food production. it may also give the shrooms a nice glowing effect.
