what model quietone chaz?
The pump is a Grundfos Quiet one Silent Aquarium Pump. They used to make them for Rainbow Lifeguard Aquatics. Grundfos no longer makes the pump. I wish they did, it is the best I have ever had. With the pump screwed to the stand, the water flow is louder than the pump, gives off very little heat and over the last 10 years has a continuous run time of about 9 years with no problems.
