Emperor® Power Filters is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from never quit I've had this filter over ten years at least, a few parts fatigued over the years but nothing a twist tie couldn't fix. Paws now petco, gave me their spare pieces, (plastic spray tubes, clips) from old filters they didn't use. I'm about to finally get a replacement. Mine is STILL working, just so much salt buildup , little broken parts etc, and reduced water flow Warrent it. Again it's well over over ten years old. My best guess is 2004, it's 17 now. Great dual bio wheel system.

My Emperor 280 needs to be replaced. I have a 30 gallon tank so the Emperor 400 seems like overkill. However, the Penguin power filters appear to be less substantial. Are there replacement impellers for the Emperor 400 or for any of the Penguins?

Asked by: Robin1
Yes, they're out there.

I am looking for a 280 power filter. It's the only PF that will fit on the back of a 42 gal hex that is powerful enough. The rest are either too wide or too weak. Are they discontinued? Any suggestions where to find one or a replacement?

Asked by: Tidy Tank
They are indeed discontinued. You might try EBay. Otherwise we recommend the Penguin 200 or the Magnum Polishing Internal Filter. BREX
