I'm wondering how many hours a day do you have your lights on your tank? Especially, the MH user's.
How many hours?

I have been using a newer bulb as a trail, they are the Reef Brite Dual Arch bulb. I run the as follows from 8am-3pm they run as a 10,000K and from 3:05pm - 8pm as a 20,000K light. I have noticed some great colors coming out of my SPS. It has been like Christmas all over again, they are 3 250w being ran by the same manufactures ballast with Coralife minarc reflectors.

I was running my MH for 12hr, but I discovered that is alot of wasted time and money. I was thinking about running straight MH for 8hrs. What do you think?

My actinic are on 10 hours a day and mh's are on 9 hours a day.
I would even take it down to 6. JMO

How fast of a time table are we talking about reducing the light time?
I went from 8 to 6 from one day to the next and then left it go for about a month and a half to see if growth was slower and then dropped it another hour and was happy with the growth still being the same.
I think you need to be concerned more if you are increasing your light cycle.

For those of you who voted on 8hrs. What hrs do you have your lights come on and turn off. Like 12:00pm to 8pm or what?
