Why do you want to keep algae in the water column?
What you are experiencing is an overgrowth of phytoplankton. It is caused by too much direct light coupled with high nutrients in the water. Is the aquarium right in front of a window? Direct sunlight can do this.

Could you also post a picture of the aquarium in question?
