Guest LisaJill Posted November 7, 2008 Share Posted November 7, 2008 Hey guys, I currently have 2x250watt MH, they run on an 8 hour cycle (11am to 7pm), and when they shut off, blue LED moonlights come on. I would like to extend this an hour for my own viewing pleasure, so keep them on until 8pm. Would this be harmful to the livestock? I've got an anemone, SPS, LPS, Softies and a new Crocea, as well as 4 small fish, shrimp, CUC, etc. I kind of wish I'd gone with some actinic or something so I could have a gradual 12 hour cycle; but I can't fit any more lights in the canopy. Thanks! Quote Link to comment Share on other sites More sharing options...
mrgreenthumb Posted November 7, 2008 Share Posted November 7, 2008 you may grow a little more algae, but i can't see it hurting any of the corals, or inhabitants Quote Link to comment Share on other sites More sharing options...
Nyles Posted November 7, 2008 Share Posted November 7, 2008 I run mine from 12:30 to 9:30 you should be fine. Some people run them upwards of 12 hours a day. Quote Link to comment Share on other sites More sharing options...
Guest LisaJill Posted November 7, 2008 Share Posted November 7, 2008 Thanks for your input! I actually wouldn't mind a bit more algae as I really want to get a starry blenny but am not getting enough algae to support one. I know, I know - be careful what you wish for.

dsoz Posted November 8, 2008 Share Posted November 8, 2008 Or turn them on an hour later in the day, then you can have the lights on an hour later. I have 6x54w T5HO over a 75g tank. These are supposed to be just about as good as some halides in light output. I have them on for almost 10 hours a day. I get a little bit of hair algae, but not enough to get frustrated about. dsoz Quote Link to comment Share on other sites More sharing options...
Guest LisaJill Posted November 8, 2008 Share Posted November 8, 2008 I'm wanting to have it on at 11 so I can look at it then too, I would just prefer a 9 hour cycle as those are the hours I want to watch the tank. Thanks all! Quote Link to comment Share on other sites More sharing options...
stylaster Posted November 9, 2008 Share Posted November 9, 2008 Mine run 13 hours a day and have no issues. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted November 10, 2008 Share Posted November 10, 2008 I run 12 hours a day on one tank, and 8 hours a day on another. I see little difference between the two. I would run both tanks for 12 hours, but my wife wants the bedroom tank off by midnight, and I'm not home before 4pm on most days.
