Different Spectrum Bulb?

[Markus]

I have a JBJ 28 HQI Nano and the lighting system on it is a 150 watt 14000°K HQI metal halide light. I see alot of talk about lighting and am curious..is there a better bulb out there for me. Alot of people are putting the blue lights on their tanks. I have some zeo's..some soft corals...xenia..open brains etc. I'll eventually purchase a clam. Any suggestions..or am i good for light?
