Ive had my tank since March the 4th, and all my fish are alive and well. Although I had a brown algae problem, it turned into a green water problem. Ive tested the tank and everything is stable, so I think the original problem is gone but the excess of algae remains. I do water changes every week on Monday of around 15 to 20 percent now to get rid of the green water. I have an amazon sword, two anubias plants, and a talanthera cardinalis plant. I havent used any chemicals yet, as I want to kill the algae naturally. Ive done blackouts but it only reduces the algae.I make sure to keep the lights on for around 10 hrs, and only feed the fish once a day. Can someone help me with other solutions?
