Now if you do setup a refugium then I agree the bio balls become obsolete, it's what I call evolving the system to the more natural approach. I did the very same thing in October of 2004. Had my 90 with wet/dry and bio balls, then added a 55 gallon refugium with chaetomorpha macro algea, then said good bye to the bio balls.
But understand I never had a problem with my bio balls, because I took care of them and the system. I never suffered from what I would call high nitrates with the 90 gallon.
The bio balls simply convert the more toxic into the less toxic so fast that it seems like bio balls produce nitrates.
Carole I don't remember ever saying that bio balls are nitrate factories, in fact I've spent years stating the opposite.
Bio-balls can work..but they also work so fast they rob the LR's ability to do the filtering...a much more efficient way..IMO. They can become a source of nitrates..and often do
That is simply a more natural way to do it, but it doesn't necessarily work fastor or more efficient.
My whole argument here is that bio balls are not bombs, factories, or even the cause of nitrates. Nitrates are simply the by-product of the nitrogen cycle no matter what surface does the conversion. The balls simply do it so fast they get a bad rap.
