Hi all. I have a 20 gal. tank. (still cycling for 8 weeks now) When it is done cycling I want to upgrade the filter. Right now I have a Top Fin for 20 gal. I bought a Whisper power filter 40. This new filter has a bio-bag and bio- foam. The one I have now just has bio-bag no foam. The old filter will be for my qt tank when I am able to set it up.
My question is, what do I have to do to put new filter in tank after cycling is finished. Do I need to do something so I don;t mess up the biological filtration or the bacteria that is needed? Thank you for your help. Probably a stuipid question but thanks anyways. Tina (After 8 weeks I don;t want to mess it up.)
