Uniclife 64 GPH Dual Outlet Aquarium Air Pump

The Uniclife UL080 is a dual outlet air pump rated at 64 GPH of air, with a pressure of 0.016 MPa on just 4 W of power. Uniclife lists it for 10 – 100 gallon freshwater and marine aquariums. It comes as a full kit, so you can unbox it and have bubbles running in minutes.

What is in the box

• The pump with two outlets
• 2 air stone discs
• 6.5-foot airline tubing
• 2 check valves and 2 connectors

That covers a basic aeration setup for one or two tanks, or one tank with two air stones.

Adjusting the air

A rotary knob controls output for both outlets. Turn it down for a gentle stream in a betta or shrimp tank, or up to drive a sponge filter like the AQUANEAT bio sponge filter. Lower settings also keep noise down.

Noise level

Uniclife lists 25 dB on the low setting and up to 45 dB at full output, about like a refrigerator hum. Place the pump on a soft surface, not on hard glass or a hollow stand, to cut vibration.

Why aeration helps

Bubbles themselves add little oxygen. The real gain comes from breaking the water surface, which lets oxygen in and carbon dioxide out. That matters most in warm, heavily stocked tanks, during medication and when the power has been out.

Keeping output strong

The pump has an air intake cotton. If airflow drops over time, that cotton is often clogged; the brand notes you can replace it yourself. Air stones also clog with minerals, so swap them every few months.

Install tips

Set the pump above the water line if you can. If it must sit lower, keep the check valves fitted the right way round so water cannot siphon back. Use extra airline tubing if the included length is short for your layout.
