New to MH Lighting Need Help
I have recently installed 3 250w XM 10K bulbs with Lumenarc reflectors in a 375 mixed reef, no SPS. I am not satisfied with the tanks/corals coloration. I probably need a little more blue spectrum. I originally was going to add some actinic blue supplements, but I am concerned about adding any more wattage that may increase the tanks temperature. I am currently running from 82.2 - 83 degrees without any fans or chillers and want to keep it that way.
My question is, Can I just change to maybe a 14K Hamilton bulb, or Radium 20K in the middle section, light that say 10am to 10pm and run the 10Ks like 2pm - 8pm? That would give me the dusk/dawn effect, but how would/do MH tanks appear when mixing bulbs like that? The middle lumenarc throws light to both ends of the 8' tank. I would truly appreciate your opinions. Thanks! |

I don't think you'd be happy with that.
Why not add a IceCap ballast with a couple VHO bulbs, and add a fan or two. Your temp is a little too high now. Or why not go with 12K or 14k bulbs all the way? I use 3x 14k 250 watt bulbs on my softy tank and use VHO actinic
