Most aquarists agree carbon is not as crucial as the marketing firms
would have you believe. I have not used it for years, except to
remove medications from the water as you mentioned.

But do use it the first time. The filter's plastic components are all
made in moulds, which use release agents (nasty) so they don't stick.
The carbon will get anything the factory rinse didn't. AFAIK, carbon is
inert, in that it does not add anything to your water (iehosphates).
