No single one thing is going to be the silver bullet for anything.
Actually, in one case it was the silver bullet. I had a tank that got no algae through the entire live of it except green water. I attribute this to it being by a window. I had a portable UV for awhile. Then I tried Purigen, thinking it wouldn't do anything. It got rid of the green water really fast. I never got green water again but sometimes I would notice that it had green spots.
That is an odd thing though. I have never had a tank that balanced get green water.
