I am switching to a canister filter on my 29 gallon community tank this saturday and I was wondering on how to transfer my BB to the canister. I know I could leave all the filters running and wait a few weeks for it to gather it's own bacteria but I was wondering if there's any other ways. Could I take the filter pads (The ones with carbon inside them), remove the carbon and just put it into my canister or would that not work? The reason I want this quicker is I gave a friend a 20 long and some filter media along with it but with the new canister filter I am giving him my old HOB filters for better filtration as the one he currently has is just enough for the current stock. If it's needed I could run them all together for a week with the media transfer to help with successfully seeding the canister. But if none of this works and risks crashing my cycle let me know and I'll just run them together for a couple weeks and still take some of the media incase. Additionally, I have 2 Sponge filters, plants and rocks and clay pots that also hold BB in the tank.
