I have a light fixture on my 125 tall that has 2 250 watt metal halides and 2 110 watt VHO lights. I run super actnic on the VHO's. I run the the VHO's from 8am to 8 pm. I only run the mh's from 10am to 3pm. This seems to work well for all my corals and keeps the tank from getting hot. I am looking for lights to brighten things up and make the tank not so blue when the mh's are off so it looks better. Or should i run the 5 hour cycle on the halides from 3-8, which is the main viewing time. Or changes things entirely. Any ideas would be apperciated. Thanks
