I noticed that there was rust colored discoloration on the carbon block wrapper and also a black substance in the bottom of the carbon canister. The best description of the black substance I can think of is if you blew black powder on a spider web. My prefilter was in need of changing but was not as clogged as I’ve seen in the past. Any idea of what would cause this?
