I currently have a 36 gallon planted tank where I had some marimo moss balls and I found Jaír Algiers on the rocks which I suspect might have came from the marimo moss balls( which I already removed) I also have some java moss that’s appear to have hair moss growing on it. I don’t want to kill my plants and I also have fish. I clean the rocks today but there’s still some on the gravel and the java moss. I already put a cover on the tank so no light can come thru. How many days do I need to keep it dark so the hair algae dies off but my plants don’t die or what else can I do??
