I have a 50 Gallon Tank, I am getting so much algae, any suggestions?

Do you have the right bulb in your light? Sometimes this is the problem and nothing will help until you get the right bulb. Go to your pet shop and get help in founding the right bulb for the tank you have set-up. You may also be getting to much natural light from in outside source. Like a window or leaving on lights in the room it is in. Try covering the tank with a sheet for a few days and see if the source of the problem is coming in the outside of the tank!
