What was the chain of events here? Were you having a gunk problem before or
after you removed all the filter elements?
I'm thinking that the beneficial bacteria population which your system
supports is suffering from a lack of real estate. They are only able to live
on the surfaces which you have left for them; namely, the canister, the
heater module and the hoses. Colonies may be so crowded that they are
existing piggy-back on top of one another. From there, it's easy to suggest
a couple of mechanisms which might cause the gunk to break free
Hope this helps, :)
