Research the symptoms of algea and try to figure out what is causing it. Is your tank close to a window? That is usually the cause I have found.

are you using tap water? if so that could be the major cause high phosphates can cause alot of problem algae growth, algae thrives on excess nutrients high nitrates, phosphates etc
