How long should I leave my lights on?

[wolffvet]

I have a 65 gallon tank that has been running for over a week now with 55 lbs. of live rock and 70 lbs. live sand and I couple of little critters that came with it and with the GARF grunge. I am just wondering how many hours a day I should run my lights. I have a 48" pc with 50/50 10k and actinic lights? Also, if I ad a refugium is it a good idea to run alternate light cycles?

I think most folks run their lights anywhere from 10-12 hrs a day.....myself I feel its important to have a consistent day/night cycle so I use timers to maintain day/night.
Personally I prefer to keep my refugium in the light 24/7...but thats a personal choice. Mine is in a seperate room and does not affect my display by having lights always on. Besides ...I've heard that with caulapers(sic)its best to keep lights on 24/7 to prevent the macro algaes from going sexual.But lots of people use an alternating schedule on refugiums with success....so whatever works for you. One thing I'd like to add...in my opinion a well set-up refugium is an extremely beneficial addition.

Most books Ive read say to run the "NEW" tank 6-8 hrs when nothing is in it, so you dont promote BAD algee....
I ran mine about 8hrs, and then did the night lights for about 2 to start...everything cycled fine..
