    Actinic vs. 50/50 vs. 10K PC bulb

    I have an outer orbit 36" dual 96W PC Actinic with a 150 watt TQI MH. I am typically not home during the day when the MH is on and I would like a less blue tank when I am home. I was wondering what the implications of changing out one of the bulbs for a 10K or 50/50 bulb would be. I was thinking this would give me the whiter look I want when I am around but wonder if a decrease in the actinic spectrum would cause problems with corals (none yet but will be starting next weekend). Near term plan softies and LPS - longer term SPS too).

    could you not just slowly change your photo period so the mh was on when you are home?

    The tank gets some natural light where it is located and so I was trying to keep the photoperiod in line with that. I don't really get to the room with the tank until around 8:00pm so to have the MH on it would need to go off around 9:00pm. I was thinking that an overall photoperiod of 6:00am (sunlight on) to 10:00 (MH off) was too long?
