    I have a 20 gallon fish tank and it grows algae like crazy. It green in color, it grow on the glass, the gravel, the real plant, and the fake plant. When a clean the tank in a day or two it is all over again. How do I get it to stop growing? Thanks *Hannah*

    finding out why you are getting it could help :)
    heres some things that can cause it

    near a window/door for sunlight
    too much wattage on your lights on the tank
    lights left on too long

    do any of these fit?

    I don't over feed my fish. I only have six 1 to 2 inch fish. It not that close to a window, but it maybe that. I really don't the wattage of the lights. I leave the lights on from 9am-10 or 11pm, because I am growing plant bulbs.

    That is too long to have the lights on...8-10 (even with plants) hours max depending on your lighting.

    Do you know what your Nitrate level is? How much light do you have over the tank?
