So i took the leap and bought a MH fixture from someone dirt cheap its a Hamilton 175 mh and 2 vho bulbs 48 inchs One of the bulbs works I ordered the other bulb . What kind of time should I leave the one mh bulb on for. Keep in mind i jumped from pcs to the metal halides. Also its a 55 gallon long tank.
