So I currently have a tetra whisper 10i in my five gallon tank that's been running for about a year now, I recently bought a Aquaclear 20 and wanted to replace my old filter with this one. Would I be able to add the bio media from the new filter and have it inside my current filter and eventually replace it? Or would I be at risk at a recycle?
