Hello I'm having a similar issue as the other poster,@MI Fish, with green algae. I haven't tried a treatment because I don't want to jeopardize the shrimp. Do you think it would? I dimmed the lights (brightened for the picture) I didn't notice a change in the algae presence. Also although an otto is in the picture, I have two, neither seem interested in eating the algae on the walls or the plants. Do they not typically eat that kind?
Thank you for your help,
