My power filter keeps shutting off on its own, and I can't figure out why. The filter is the type that hangs behind the tank, poor water back into the tank, has a tube that sucks water from the tank, and the tube has some sorta of spiny thing that creates the suction on one end.
The way I've been fixing it is by removing the tube and resetting it, or unplugging and replugging the power, turning it on and off basically. Sometimes I can catch it making this rumbling/scratching sound a little while before it shuts itself off. That's pretty much all i know. Anyone know what's going on? Can I fix this thing? It cost me enough money that I really want to avoid junking it.
