I used to have a BIG problem with algae overgrowth in my aquarium. However, I tried different methods and asked other tank owners for advice, like you.
Later, after a few days/weeks of using the recommended methods....I noticed it had cleared up! I finally had sparkling glass and fresh, clean water. Whew...what a sigh of relief it was to take care of this unsighly problem.
Here is a Step-By-Step article that I wrote to help others who are going through what I went through with aquarium algae. It is posted below.
