Aquarium Advice FINatic
My friend is setting up a larger tank and upgraded to MH's. He asked me a question and I don't know the answer since I have only had PC and VHO from day 1. I know that a lot of MH's usually run with atinics, and his setup has something different than anything I have heard of. He has a 150g like mine except it's 29" high (mines only 18"), anyway, he's got 3 400w blue? (I'm not sure if thats right, but it's what he said) 20,000k and 4, yes 4 110 VHO bulbs, 2 are white atnic and 2 are blue atinic. To me that seems kinda weird to have that many VHO's but, I don't know much about MH's. His question is can he run the halides by themselves during the day and the atnics only in the morning and at night??? He said that the MH's already have the blue spectrum's, but then why the VHO's? I know corals need the blue spectrum, but what I can't answer is if the MH's already have that. I always thought you needed both the atnics and MH's??? Can someone explain this to me?
