Light Cycle

Wondering how long I can run MH's. I have a 120 gallon (4' x 2' x 2') and presently operate the flourescents about 12 hours per day and the MH's about 6 hours in the middle. Any reason I couldn't run the MH's longer? It's kind of dark and gloomy with just the flourescents.

BTW the light fixture is the 48 Coralife with lunar LED's, actinic and regular flourescent. and 2 x 150W MH.

I dont see why not. I probably would not go over 8 hrs though.


You can view many of my fish and corals in my photo albums in my profile.
