my whisper exterior power filter has lost its biofilm. any ideas on how to re-establish this? my tank has been running along quite well for many years, but all the sudden i'm having all kinds of problems due to the lack of biofilm in my filter.

The pH is 7.0, and every thing else tests well. I'm sure that the problems i'm having with my tank is the lack of bio-film on my filter.
