bad quality carbon, or you didnt wash it well.
is the skimmer still working?
you may need to wipe glass from time to time.

black diamond carbon, used this stuff for years. 20 min rinse is a long soak for sure. skimmer is running like crazy thick black crap

I have never heard of carbon doing that after a 20 min rinse. If you have one avaiable you might want to hang a canister on the tank to assist in the clean up.
