>What sort of biofilm? Photosynthetic? Nitrifying? How thick is it? Is it
flat or on sand? The type of organisms will make a big difference in the
type of measurements you make to monitor metabolic activity.
We used microelectrodes (usually pH and oxygen) to monitor activity at
different levels within biofilms, but without a bit more detail, it's hard
to know what to suggest.
