Right now, my new goldfish tank is still cycling fish-in (tank about 6 weeks old), but down the road I'm thinking of swapping out the carbon for additional filter media (going to wait until the cycle has been established in a while, though, as some of the bacteria could be trying to colonize the carbon bags - made the mistake of swapping out the carbon at week 3 and set myself back a bit).
When the time comes, does the type of media matter? I'm guessing not since it's just a structure that the bacteria adhere to, but I want to double-check.
I'm running a Marineland C-220 canister. For those unfamiliar, from bottom to top it's:
Large-gauge mechanical filter pad (traps bigger particles)
Carbon bags
Bio-balls
Ceramic rings
Filter floss (polishing) pad (traps the smaller particles)
Other than waiting for an established cycle, and only swapping out one of the two carbon bags at a time, does the replacement media matter? More ceramic rings? Some sponge? Take my pick?
Thanks.
