Sorry to be a pain again, I think you guys and girls are going to get fed up with me keep asking daft question.
But I have another tank that I shall be setting up in the near future and I have heard about putting mature filter media in the new tank which will give it a bit of a kick start. But which bit do I use? Am I right in thinking that I use the white spongy bit at the top of the old filter in the new filter or have I got the wrong end of the stick?
I hope some kind person(s) can set this right. Once again many thanks and sorry for being quite dumb
