I'm thinking no one here probably has one, but on the off chance...
I've been given a Fluval 3 Power filter. It hangs on the tank vertically. I've cleaned the filter well (I hope) and have had it running in a bucket of clean water to rinse it out. There are 3 while plastic pieces that fit together and attach to a piece of plastic that protects the impeller so that there's a long tube-like strainer going down the chamber. The only other thing that's come with it is a polyester "sleeve" that fits in the chamber around the tub-like strainer. No directions came with it, and the person who gave it to me can't remember if it needs anything else.
I have the feeling that this filter is a precursor to the Fluval Plus series. I can't find it online or in petstores like Petsmart or Petco. Does anyone know anything about this filter?
