    Imo, you are going to need more light than that. I would try for 4-5 watts per gallon to have good coralline algae growth. In addition, you will need high calcium and strontium levels and a moderate water flow. A product called "Purple Up" added to your tank will also help with coralline algae growth.

    I have 2-65watt daylight and dual 65 watt actinic bulb light that is producing corilline algae now. I use half the dose for PurpleUp everyday and it seems to be coming to life. Most will tell you that MH light are much better and they are but some people like me only have a ceritain budget I get from Mommy and that was all I could afford at the time. The model is in my signature.

    Not for growing coralline they're not. Coralline grows best in low, blue actinic lighting. :)

    Ill do the same purchase a compact i guess thats an affordable way to go if it does the same job producing coralline over a MH. do think a MH would produce faster algae growth than a compact or the same? thanks!

    Do you have or plan on keeping corals? If so, you should focus your attention on keeping your corals healthy and not focus so much attention on coralline algae. The coralline algae will come in time.
    I have coralline algae growing in both my tanks and I am running metal halides in both. In my 75 gallon tank I also have coralline algae under 5watts per gallon of power compact lighting-50/50 bulbs!!!!
    Just keep the calcium and strontium level up and water flow as I mentioned above.
    Reef1, the lighting fixture you are talking about should be sufficient in establishing coralline algae with the other variables being met!
