Whats better 50/50 og 10K?

[125intx]

I have no corals just LR. My coralline is just about gone due to the lack of lights. I am about to go buy either a 50/50 or 10K PC 96w. What would be better to promote the coralline groth to come back?
Thanks!!
Chris

If all you have is the one bulb on the tank go with the 50/50 bulb. It will give you all the spectrums needed and you wont have to worry about a bad algae bloom if you use just a 10k bulb. If you have a dual bulb setup on the tank then go with 1 10k bulb and the othe actinic.
