i think the best bulb might be the ATI Blue+

ATI Blue Plus and if you want to make pink or purple colors pop better run a UVL 75/25 with it. Kinda a purple dusk/dawn effect that I think is pretty cool.
This is a shot of my tank running with the 75/25 in front and a Blue Plus in the rear. with the blue in front the dusk/dawn would look less purple. It's hard to tell in that picture but it looks like the upper half of the tank is blue and the lower is purple.
