Adding a new MH light.

masonicman · 01/13/2008, 06:33 PM

I just got my hands on a 175W small MH light. I want to run this light in conjunction with my existing 360W PC lights. I run my lights 10:30AM til 8:00PM. Actinic on first then daylight and vice versus for off. When and how long should I run this new MH light?

Depending on your corals, you would want to start running it 1hr mid day and adding more and more time from there, so you dont shock your corals. Ultimately 8hs is usually enough.
