I have 4 powerheads that are over 5 years old. Two of them are made by penguin and the other two are aqua clear. When I plug them in, the motor spins the propeller, however, they don't move any water. I have connected the air line and the output end is above tbe water. I have checked that the tubing is not clogged and that the intake isn't clogged.
Hopefully this doesn't mean they are burnt out? Is there anything else I can try? Thanks for the help.
