    That's an interesting question. Whether or not you're providing too much light would depend on several things. A couple of which are.

    1) The type of lighting. T5's, CPs, etc
    2) If you're using cO2 or not.
    3) Exactly what you're feeding the plants. Feeding meaning trace elements, nitrogen, potassium, phosphorus, micro-nutrients like iron, and other trace elements.

    Algae is less picky and if you're providing too much light and not enough of what your plants need the algae will take over and the plants will die. If that happens then I'd say you're providing too much light.

    Also you'll want to keep your fish in mind. Too much light can cause them to be stressed.

    Yeah as long as fish aren't in question unless you have an algae problem I don't think you have to worry about too many watts per gallon

    Different plants have different light requirements so as long as the algae is not taking over and the plants are growing and the right color there should be no problem. You say you use cO2 so anything above 3 to 4 watts per gallon should be thriving. As long as you don't overdose the cO2 your on the right track.
