Check your riser tube, it may have a lot of "gunk" in it that is slowing the
waterflow.... If that doesn't work, check the actual bio wheel frame
itself. Make sure it spins freely. You also want to make sure that your
tube is pushed all the way into your filter (push down on the top of the
riser tube). You can lift this tube up and down to slow the waterflow
during feeding times and such.....

The wheels on my Penguin 330 aren't turning. I switched out the filter
media
& made sure there was nothing blocking the wheels, as per the
troubleshooting guide in the manual. Anything else I can check? Maybe the
flow of water has decreased for some reason? The whole thing is maybe two
months old.

thanks
