As I \mentioned in a prvious thread

Algae needs Nitrogen, phosphate, potassium, and light to survive. So keep things in check and you can get rid of the algae problem. Never use a chemical to treat algae problem unless its your last reort. Also remeber algaecides are harmful to invertabrates, scaleless fish and plants. I used "jungle" algae be gone one time to get rid of 100% overgrown algea on my cave rocks. 2 weeks later and 2 water changes it was all gone. But it killed 90% of my Java moss which was attached to a peice of driftwood. I keept the dose below the recomendation it worked but I feel bad cause it probally was stressing out the fish with the chemical also. I then made sure not to overfeed my fish and I have not had an algae probelm since and that was many, many , many months ago.
