So I just received a new 12g jbj tank...i was wondering if these were all ready to go as far as the filtration is concerned. As you all may know it comes with sponges in the first chamber...second chamber has the bio balls, ceramic rings, and carbon. is this ok to leave it as is? Should I remove any of this media? Or can I just fill it with water now
