With a pressure rating of 0.025 MPa, this pump pushes air effectively down to approximately 24 inches (60 cm). For deeper tanks (e.g., 75-gallon tall tanks), you will need a higher-pressure pump, but for standard 20-gallon longs or 40-gallon breeders, the Kd-a180 is perfect.
If you use a check valve and keep the filter clean, expect 2–3 years of 24/7 operation.
