    Hi guys,
    I'm in the process of installing 3 80W T5 lights (2 white,1 blue) on my tank.:thumbup:
    I allready have 3 54W T5 lights (2 white,1 blue).

    Can i just switch on the new lights, or should this be done over a period of time. In other words first 1 light for a hour a day, then 2 lights, then all 3 lights..?

    I'd switch all lights on and just decrease the photoperiod. Then each day increase it a bit until you're back to normal :thumbup:

    I dont think T5's are too much of a problem unless you have the ATI power Module.

    I run only T5's and new corals always take a couple of days to get used to the 54w 18000k. You firstly see them loosing a little colour, a week later the colour starts coming back and all is happy.
