    Just curious to see what others do.

    How many hours do you leave your metal halides on during the day? What spectrum are the bulbs, and what are the watts, how many lamps and what size is your tank?

    Wow, it looks like my 4.5 hours of halides + actinic is low.

    4:00pm - actinics on
    5:00pm - MH + actinics on
    9:30pm - MH off
    11:00pm - actinic off

    I think I'll slowly raise it up .... keep em coming guys :)

    I cant remember where I read... but a group of reefers actually have a low light period and have had better growth results with their coral. :-/
