-the filter material should be cleaned in
extracted tank water as you clean filter
material in any other power filter.

I'm new to the Bio-Wheel myself and wonder if I could ask for a
clarification.

I have the Penguin Mini Bio-Wheel running on a small tank with two small
goldfish. After setting it up two weeks ago it's performing marvelously.

How often, though, does one change the square, flat filter cartridge that
fits into the external compartment? Do you just rinse this and reuse a few
times, or change it for a new one every couple weeks?

Your info is much appreciated. My fish are much livelier since introducing
this filter.
