What is that stuff even called? its the material that's in the sump between the chambers to help eliminate the bubbles as the water overflows to the return. Anyway, I've not touched it. Figured I might need to clean it now and again. Do you? How? Why? Benefits of cleaning? There's got to be some life in that with copepods, etc. Hate to kill that.
