I went to Aquarium Fish Depot and they suggested I get a water saturater. I can't remember exactly what it is called. It was 180 dollars, but my granda decided to give me an early birthday present. I talked to the owner, Sam, and he uses one on every single show tank they have. He has a 150 community planted and he used it on that to prevent algae growth. He said it took 7 days for the algae to stop growing. This prevents algae from growing but does not make the algae go away. I need to scrub the algae off manually, but after that, the algae will not grow. It is guaranteed this way. If it doesn't work within a month, I can bring it back. I found Rid-x a few weeks ago and dosed it, but this water thing does not work with fish medicine. I set this thing up this morning. I can get more information on it later, as the manual only provided information for how to set it up
