hey guys ive bought a new nano tank but it has carbon media with it also , Instruction says to wash before use . But ive been washing for nearly an hour and its still black coming out of the bag its held in. How clean do i need to get it before i can add it to my filter? thanks

It will contine to flake off dust.
After an hour, I would just put it in the filter.
Other than using it to remove meds, I do not use carbon here.

Same with us, we only use it for clearing meds. What I'd do to clear the carbon is swish that bag around in a little bowl of removed tank water.
