Used filter question
 
I just bought a 20 gallon aquarium that had been previously used at a pet store. The filter that came with it is a Second Nature Whisper Power Filter. I'm pretty new to fish keeping, but I thought that in order to successfully cycle a tank, there needs to be a bio wheel or some other bio filter component to the filter for the bacteria to grow on. This filter only has the removable cartridge that I would need to change periodically. Could someone clear up my confusion?

The bacteria needed for tanks to cycle or mature grows on everything in the tank. Rocks, decorations, gravel. and the filter. It matters little what type filter. Biowheels simply provide more surface area for bacteria to colonize. It is important not to replace the filter until after the tank has cycled or matured. If it becomes clogged or water flow is slowed down. Then you can swish it around in aquarium water that you take out during water changes. Do not use tap water . You really don't want to disturb it if you can keep from it. Overfeeding uaually clogs them up. Once a day feeding if you are cycling with fish is plenty. :wink:

If you cut open the floss on the filter media a little, and shake out the carbon then you can use it for way longer. You should still replace it sometimes. But no where near as often as if you had carbon in it.

Is there some kind of bigger frame that the cartridges attach to that looks like it holds something else? They sell coarse black biofilters that fit in those but I'm not clear on where to find them (I got a bunch extra when I bought my used 29 gallon off eBay).
