If you want. Just use different means to keep bacteria in the tank.

Any over the side filter will work. You don't have to get a crazy expensive canister type. I just recommend getting one rated for about twice the gallons it will be used for. Some take 2 of the cheap slide-in cartridge filters. For the over the side filters, these are the ones I recommend. That way you pull one cartridge when it gets full of gunk and replace it with a new one. Do the other cartridge 3-4 weeks later and so on. Only change one at a time. These will keep your water clear just as good as a canister if it's rated to filter enough water. Get one for 50/55 gal for the 29 gal tank.

That way you are not removing all the good bacteria at once. Especially in an aquarium which is not yet established, and you only have to change one filter once a month.
