I'm trying to decide between these two lights. The tank is a 46 gallon bowfront, 36 inches wide, 15 inches deep. The outer Oribit is a 150 MH
with 2 96w compact fluorescents and 4 lunar lights for a total of 342 watts. The Nova Extreme pro has 3 39w 10,000k, and 3 39w 460 actinic lights for a total of 234 watts. The NOva extreme pro is about $150 cheaper. Is there any reason I should with the more expensive Mh
combo? Is 342 watts overkill? Would I have to add a fan?
