Hey all, what I thought was just plain hair algae has turned into this! Is this green cyano? I bought new lights last week and it has appeared on the back of one of my rocks and it’s starting to wrap around to the front.
I believe a strain of cyano. They do not always have to be red is my understanding. If you point a pump at it will I come off? What kind of nitrate and phosphate readings are you seeing?
