    Lighting for a 25 gallon reef

    I am starting up a 25g reef tank and am planning on using 2x55w Compact Flourescent bulbs, one 10000k and the other Actinic. This would give me about 4.4wpg. The tank is only 16" high. With a 3" sand bed the bottom will only be about 14" from the lights.

    Is this enough light to have some corals? If so what types would be sufficient under htis lighting?

    Thanks,

    Chris

    One 55 watt cf (50/50) is "enough for some corals".

    It is a matter of what corals in particular you are looking at.

    You could certainly have enough for softy corals, like mushrooms, xenia, zoos, etc.

    Watt/gallon isn't a particularilly good measuremtn to go by.

    Anyway with those lights you'll be able to keep softies and some tougher lps like a candy cane. SPS you'll need MH lights for.

    I'd suggest if you're thinking about buying a specific coral, just post back here & ask if it'll be okay under your lights.

    Cheers!
    There is nothing so permanent as a temporary measure.

    Thnaks for the replies. I haven't thought about what corals I want yet. I am just planning out the tank and wanted to make sure the lights would be okay. I didn't want to have to redo them after becasue there wasn't enough.

    5 watts per gallon minimum for a reef aquarium.

    Ironman - it's a good rule of thumb, but would you count the actinic supplimentation into that theory?

    Tank depth and intended livestock are probably the primary considerations.

    Yes I do consider actinics as part of the equation. Now I'm not saying that you could strictly use 500 watts of actinics only.

    I'm using 12,000K MH's which are blue in colour. I also supplement with 2 VHO T12 actinics to simulate dawn and dusk.
