souperman Posted December 11, 2011 Share Posted December 11, 2011 I have a 6 lamp T5 Tek fixture above my 90G and have been running the main lights 10 hours a day with the 2 dawn, dusk bulbs on an extra 2 hours before they come on and after they go off. Does this sound like too long? I have mostly SPS frags at this point as the tank isn't even 4 months old. Link to comment Share on other sites More sharing options...
Jeramy Posted December 11, 2011 Share Posted December 11, 2011 I have 4 6 watt stunner strips that I run 12 on 12 off and a light on my fuge that runs at night. Link to comment Share on other sites More sharing options...

Reefsickness Posted December 11, 2011 Share Posted December 11, 2011 run your lights for 8 hours during the times you like to watch your tank Link to comment Share on other sites More sharing options...
souperman Posted December 11, 2011 Author Share Posted December 11, 2011 I'm wondering if 10 hours is too long. Seems like a lot of people run them 12 and 8, so I thought I'd split the difference. Link to comment Share on other sites More sharing options...
reefnjunkie Posted December 11, 2011 Share Posted December 11, 2011 10 is not to long-I used to run 12 hours of actinics with 10 of the halides and my tank is only SPS I kmow run 10 hours total, with an hour at each end my Royal Nlues onlt-My tank is now all LED and after a month or so I will make it 12 hours again with the RB on an hour before and after the whites turn off. You are fine with the way your are, I am just limiting the time now so I dont get more "green" on the rocks, the tanks new and coraline is growing fast but I want to wait until it comes in more on the rocks before increasing the photo period Link to comment Share on other sites More sharing options...
