That's interesting. I've never read anyone recommending carbon be added after the tank is established. All I've read says to use carbon initially until everything comes into equilibrium.The use of activated carbon is not needed or recommended until after establishment of both nitrosomanas and nitrobacter colonies. This takes 4-6 weeks. Once you see a measurable level of nitrates, ammonia is near zero and nitrites are coming down you can begin partial water changes and introduce the use of activated carbon. Always use a good carbon, that will crackle, hiss and get hot when rinsed with distilled water. If your home water is chlorinated do NOT use it to rinse your carbon! Carbon should always be rinsed to remove excessive dust before adding it to the filter system.
I haven't run any carbon in my tank for about a year now after switching from a HOB to a canister. Haven't had any issues.
