Bio filter in established planted tank
My wife has been dabbling in a planted aquarium with discus for about a year now. She wants to use a form of biological filtration like fluval biomax. If she adds it to her filtration will it cycle the tank again? The tank is over a year old now.

Re: Bio filter in established planted tank
It shouldn't. If the Fluval is merely being added to the existing filtration, the bacterial colony that's already established in the tank should expand (somewhat) to populate the media in the new bio-filter. But there should not be an ammonia or nitrite rise.

Re: Bio filter in established planted tank
I agree with Doug. I would also say if you don't have issue now, I'm not sure what you expect to gain.
