If you buy a new filter, you can keep the old one running while the new one gets established. And by the way, welcome to FP. Jim Water, taken in moderation, cannot hurt anybody. -- Mark Twain

Not a problem at all but you must keep the old filter running for at least a month same may say less but I would prefer to run it until it has its own good bacteria system running. To help it along you can add a good Bio starter/cycle at every water change this will get it going and keep the good bacteria in its origional state. *Have a look in [link=My Profile] http://www.fishprofiles.com/forums/member.aspx?id=1935[/link] for my tank info* Look here for my Betta 11Gal Desktop & Placidity 5ft Community Tank Photos Keith Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

Just remember that bacteria die within a few hours with no oxygenated water flowing by so don't leave the old one turned off while setting up the new one.

The huge majority of the bacterial colonies that support the nitrogen cycle live in the tank and not the filter. They live on each grain of gravel, on the surfaces of the tank, and on any ornaments or rocks. I would not worry about it at all.

But if you're worried about it, run the two together for a while till it gets some bacteria built up, won't hurt anything.
