Let's stay on point here. No one is talking about the carbon releasing ALL that it has adsorbed. That's been established as a myth, yes, because it is one - carbon will not spontaneously dump everything. That claim was never made in this thread, however. The point of discussion, up to now has been whether or not things can be bumped out.
There is great shortage of ACTUAL science in fish keeping. There is a lot of uncited information (like in the link) that gets copied and pasted and parroted. This is something that is pervasive in the hobby, across all categories. Just because you read something over and over (in fish keeping publications?) doesn't make it true, especially when one source is just copying another. This occurs in fish profiles ALL THE TIME, and it doesn't end there.
