    lighting for macro

    Is a metal halide to strong of a light for macro algae to grow? I hooked one up and am going to the fish store tommorow to pick up some macro. I wanted to use up my crap. And don't want to waste more money on lighting.

    if your talking about something like spagethi macro, i would say yes.. normal no tubes or incandescent light is well enough and might infact grow faster and stronger due to lower K ratings

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    Even a 60 Watt household bulb is Ok for macro...why have the extra expense of running MH in a refugium....I use a single 40 watt flourescent on mine
    The only thing two reef keepers will agree on, is what the third reef keeper is doing wrong!
