Greenish water help

[edwardclaxton]

My friend has a 75 gal saltwater tank, and recently his water has turned to a greenish color. What could it be? Recently added a new light in which his water was a little green before but more greener after light has been installed. He has an anemone clown a small button ployp frag and a small zoanthid frag. Is it an algea bloom, could it be the fact that is tank in almost directly in front of a window? Any ideas what it could be and how to fix it thanks..

Has he or she done water changes? The water will turn a dirty color if it's not refreshed.

He did last night but I havnt seen it since I helped him do it.

He did another water change but its not helping much any other ideas

It will take more then one water change to stop it. Need to export the excess nutrients out of the tank then the water should clear. Maybe some carbon could help as well.
