Lifegard Quiet One 400

Lifegard Aquatics Quiet One 400 – Compact Pump with Low Noise and Steady Flow

The Quiet One 400 by Lifegard Aquatics is a small but dependable water pump designed for light-duty circulation in aquariums, fountains, and hydroponic systems. Rated at 103 gallons per hour, it provides gentle, continuous flow without drawing much attention. Most users pick it for quiet setups—places where noise matters more than brute force.

This pump is suitable for both submerged and inline (external) use. That flexibility makes it a go-to option for people working with tight cabinet space or low-clearance fountain basins. Whether you're running it behind a reef tank or under a countertop hydro unit, it keeps things moving without creating extra noise or heat.

It runs cool. When used dry, it uses air channels to prevent overheating. When submerged, the surrounding water handles that job. Either way, it stays quiet—no loud hum, no grinding sounds, and no surprises.

The Lifegard Quiet One 400 Pro is Built for Practical Use

The intake includes a removable grill to keep out debris and protect livestock. Internal access is simple—no tiny screws or specialty tools required. Cleaning the impeller only takes a few minutes, and the flow dial on the front lets you cut back output when needed.

If you're using it to feed a filter chamber or move water through a small loop, the adjustable flow helps you avoid overdoing it. Head height maxes out at 2.1 feet, so this isn't built for vertical lifts or long tubing runs. It's better for short horizontal movement, sump returns on nano tanks, or recirculation in hydro systems.

Where It Fits

• Small aquariums (saltwater or freshwater)

• Shrimp tanks or breeding setups needing light turnover

• Indoor hydroponic racks or propagation trays

• Tabletop fountains and decorative water features

• Utility circulation where silence is important
