T5 bulb question

I thought I posted this somewhere earlier but can't find it so, if I repeat myself, please forgive. We'd like to try new bulbs for our T-5 fixture to see if it helps. Some of our corals are translucent. Since we're ordering from F&S next week, I thought now would be the time. I'm thinking of two actinic white 12,000K T-5 HO Flourescents (they are the highest K I find at F&S) and thought I'd pair them with two of the T-5 HO Reef Blue 10,000K Flourescent. Not sure of the brand of either. They have Aquasun which I heard are good but only 10,000k. Any suggestions?

I just replaced my bulbs which are T12. I got them from hello lights and they are aquasun bulbs. It says that they are good for 4500 hours. I like them but want to switch to T5 sometime down the road.
