I'm not sure what a c-3 is, am assuming it's a hang on back filter. I have 2 hobs on mine and it lets me clean one once in a while with out disturbing the good bacteria in the other and causing a mini cycle. Also, I don't buy filter cartridges, I use media sponges and just rinse them in tank water. It's much cheaper and I never throw out the bacteria on the sponges as I would replacing the cartridges.
