I have a couple of questions, currently I have a 55 gal thats been setup for a couple of years I have a couple of JD"s about 5-6 inches and a couple of convicts with a TetraTec pf 500 and a smaller Aqueon. My 180 has a sump. First question is Can I take the media out of the filters running now and maybe put some gravel in a pouch or something and put that in the sump and not have to worry about a cycle? Second, If I hang the Bio-Balls that came with the sump in my current tank will they start collecting some bateria? thanks
