Chances are you have Coraline algae. A calcium type. A razor blade will work. But you need to be careful not to scratch your glass (very easy to do!). There are plastic blades available, Kent makes the one I have. This works well if you remember to clean the glass frequently.

If your tank looks like mine, a 3" border around the edges, then the razor blade is likely the best option.

yeah i have a 14 gallon bio cube that i will be taking pictures of tomorrow morning so you guys can see what I'm talking about.. its like little small green spots all over the glass but hopefully the pictures will show what I'm talking about..

Did you say 14 gallon tank?
Snails will eat algae on your glass.
Razor/handle you can find at most fish stores-relatively cheap.

What do you think is the reason for the algae outbreak? Phosphates in water? Sunlight hitting your tank? While I agree it is good to remove the bad algae, I think that the CAUSE for the sudden change is worth investigating.
