Re: Re: Bioballs, wheels, a lot of hooey about a lot of gooey?

Scott H. asked:
"Does anyone have any hard data on how the various versions of
biofilters perform, how much biofiletering they actually accomplish?"

See Stephen Spotte, "Seawater Aquariums: The Captive Environment" (1979). I
can't put my hands on my copy right now, but as I recall he had a lot of
information about the rates of biofiltration possible with a number of
different media.
