I would do 10-15% water changes every few days.
Do you have you any live plants, they help use up the stuff that feeds the algae so it starves.
Also you may be over feeding the fish, Remember a fish's stomach is ONLY a big as one of it's eyes.

did it get that way gradually or real fast? i'd be doing large water changes daily and perhaps even clean the substrata and decor a little at a time, along with the inside glass and filter. not all at once or it'd kill the cycle, but a bit at a time plus water changes and a reduction in food might work.
