So somewhere along the line I got grape caulerpa in my nano. Unfortunately, it's on the largest rock in the tank and is a real hassle to get out. I tried removing as much as possible, then soaked it in hot water and scrubbed the rock with a bristle brush. However, about a week later the rock is covered in caulerpa again. Is there anything I can put in there that will eat it? I really want to avoid boiling the rock.
thanks
