    Hi

    What is the best T5 lighting system for a 4ft tank? At the moment I'm running six bulbs,

    Reeftek
    4 X T5 54w -12000 k
    2 X T5 54w -Actinic...

    I want to bring out the color of the corals more.

    I see you get actinic, blue and pure actinic bulbs...

    What should I go for?

    My 2c:

    Have 3x 12000K 54W
    Have 2x Actinic 54W
    and 1x Pure Actinic (think only Giesemann manufatures them, not sure though);)

    So all you do basically is replace your one 12000k with a Pure Actinic

    The Pure Actinic T5's are 320Nm and below, thus they are actually purple. They bring out massive fluoresence in blue and green corals, and any metallic coral for that matter. I use one on my tank, and it is pure magic!!!

    Thanx Jaco

    I was thinking of doing it that way but was not quite sure. Can you run your tank only on actinics and one white?

    All depends on what corals you are keeping and at what depths. I have kept zoa's, musrhooms, kenya tree and star polyps under only actinics, with one 15000K T5. They all did very well, and I had no issues, but I think they might have grown faster with more "white" light.
