Re: Time for new lamps - 400w Single Ended

All 10K bulbs are gonna look a little bit yellowish. That's where actinic supplementation comes in. You get better quality MH lighting and PAR from the 10K bulbs, yet the actinics give the tank that pleasant bluish color we tend to prefer, AND, it gives your corals a nice phosphorescent "POP" from the actinic radiation...
