All of a sudden like in the past 2 or 3 weeks, my water has gone from crystal clear to this terrible mucky green color. I still do regular water changes and the test levels come out OK, so I am pretty sure this is just a very bad case of algae. I can't figure out what is causing it though. The tank has been in the same spot since I set it up in July. There is 1 tiny window in the front door that kind of shines on it during the day, but it has never caused algae before. I leave the tank light on from about 7:30 in the morning until 4:00 or 5:00pm. I just started using a new food at about the time that the tank started turning green, but I'm not sure how that would cause this. I am using Wardley flakes if that means anything. Does anyone have any advice as to what could be causing this? Thanks in advance!
