I got my new tank from craiglist and it came with a Penguin 100B. It was disastrous to say the least and at least once a day I was taking it apart and rinsing the impeller to get the pump working again. Today, it finally bit the dust. I replaced it with a new Penguin 100B and twice now I've had to take it apart, mess with the impeller, and put it back together. This filter is becoming a nightmare.
I use sand substrate, but there isn't a correlation between stirring up the sand and the filter stopping. My only other guess is that I had been keeping a smaller, second filter cartridge from my other tank in with the new cartridge for cycling purposes. The tank cycled, but I left the small cartridge in anyway for extra bacteria media. Could this be affecting the filter?
I've taken it out... considering I had to take it apart again just a few minutes ago, and see if it makes a difference.
Anyone have any experience with the Penguin? I read reviews and saw where some people had trouble with it, but the overwhelming responses tended to be positive. I'm starting to question that unless I am missing something...
