Just wanted to understand some things. Basically i thought biballs, in a wet dry filter where there to create a large surface area where areobic bacteria could grow and in turn breakdown No3 into nitrogen gas. Some people have told me that using bioballs in such a system can raise No3 levels, and this is why they dont use them in a reef tank. is this true, if so how and why?
Quick second question, what's the dif. between nitrate reducers and the bioball section of a wet dry.
TIA Josh
