Re: Too much biological filtration?
Just wanted to underscore what Scott said. The bacteria can only exist at
levels equal to the nutrient source. One fish in a large tank would only
be able to sustain a certain amount of bacteria, regardless of the filter
surface area, flow rate, oxygen levels etc. Having a fast turnover does
not necessarily mean the filter is removing more waste. Sometimes the flow
can be too fast for the bacteria to be effective.
