Is this carbon coated?

Our Classic Pond Filter Pad fibers are not carbon coated. The filter pad is black from a thick coating of latex which gives it strength and durability. Since our filter pads will last much longer than carbon in a pond we recommend using activated carbon in a mesh bag which can be replaced on a regular basis.
