MaeDae871 Posted June 11, 2021 Share Posted June 11, 2021 (edited) Hello, I have a 75g that I recently did a 25% (roughly) water change on. It kick started an algae bloom, and I am not sure what to do. Usually what I do is just darken out the tank and hope for the best. But I am afraid that if I do that, and all of the algae abruptly dies, I will have a major ammonia spike. I have a young Oscar in there at the moment, and I know they're highly sensitive to ammonia. Am I overthinking this, and should just go ahead with a black out? Or are there any other routes I can take to clear this up? Any advice would be greatly appreciated!
