I want to change my wet/dry into a refergium. I know everyone talks about bio balls being bad, but I've had them in my system for over a year and (so far) had no problems. If I remove the bio balls my wet dry makes a ton of noise and the wife don't like. I thought about putting plants in there to stop the noise but I would need a ton of seaweed or other plants. Is it possible to change the wet / dry into a referigum or should I try to figure out how to convert a 10 gal tank into one?? Plus my tank makes very little noise with the set up now and I would hate to change things and regret it later.
