Well I'm still confused on this. I've been reading and reading and having used PCs for 5 years I still don't get all the differences in MH
bulbs. I don't want to spend an arm and a leg if I can help it, and it looks to me that I will need at least 3 400W MH
bulbs and perhaps I can use a pair of PCs that I currently have for the actinic blue.
So the question is... what kelvin rating am I looking for in MH
bulbs? I know this is somewhat a matter of personal preference. I now have a pair of 10k coralife PCs and a pair of 7100k actinics. I like the color. Would three 10k MH
bulbs and those same pair of acitnics do? What about the KIND of MH
bulb? There are single ended, double ended... "reef star system," etc. It's all quite confusing, I feel. Help me out
