Is carbon supposed to come out of the filter and into the tank?

I have a fluval 306 external filter...bout 2 months old and carbon has been getting in the water since setup...

No, the carbon shouldn't be getting into your tank. somethings not right.

You have to put the carbon into a mesh bag. Same if you use GFO with a canister.
