it looks like a small bit of xenia on the rocks. and +1 to the above poster. My first tank crashed due to me rushing my livestock, the tank can't handle it and then everything dies. Also get some gfo
edit- spend the money on separate reactors, the time in between changing will make it expensive if you mix them
thats what i did, got two separate. I'm sure I heard that gfo will last longer then carbon will.
