Ok I have a 120 gallon 4x2x2 and I haev been having a hard time on figuring out what type of lighting combo I want to have. I will be having mainly SPS's and I was thinking 2 400 10k watt ushios and 2 110 watt actinic VHO's. Would this cause a heating problem? this would be in a open back canopy with 2 4" fans on the sides about 10" from the watter. Would I need a chiller? Or I was also think 2 250watt XM 10k and 2 110wt VHO actinics. And do 400's cost a lot more on the electric bill than 250's?
Thanks.
Thanks.
