[memphisrb]

I am currently running 2 65w 50/50 pc bulbs over my 35g reef. I will soon be adding an additional 2 65w bulbs. Any suggestions on what type pc bulb to purchase, ie 2 more 50/50, two 10000k, one 10000k and one blue. The reason behind your suggestion would be helpfull. thx in advance. rb

What all is in the tank?

I'd go with one actinic and one 10000K. Assuming they're on separate switches, you can have the actinics come on earlier and go off later, simulating something like dawn and dusk.
