I've seen photos. The microbes aren't eating the charcoal; they are using all
the pore space in it to adhere to, and consuming nutrients that float past in
soil moisture. The charcoal itself is more or less inert. Same as in a reed
bed; the bugs cling to the gravel, and they sure aren't eating that.
