Adjustable Air Pump

Adjustable Air Pump

The ATP Adjustable Air Pump has a control dial to adjust for a 20 to 50 gallon aquarium. ATP pumps are affordable and low noise – though there is always a little sound with air pumps. Regular air flow not only introduces the air into the water essential for fish respiration, the flow also helps balance pH and provides a gentle water current. Airstone and tubing sold separately.
