AquaMiracle Aquarium Powerhead Pump 135 GPH for 10–40 Gallon Tanks | Aeration & Circulation

Compact, Submersible Powerhead for 10–40 Gallon Aquariums

The AquaMiracle Aquarium Powerhead Pump is a compact, submersible circulator designed to deliver reliable water movement without occupying precious tank space. Its epoxy-sealed motor is built to withstand immersion and has been tested to minimize the risk of water leakage, helping you maintain a safe, steady setup.

Core Performance

Enjoy a robust flow in a small package: up to 135 GPH (500 L/H) with a 2.5 ft (0.75 m) lift, while drawing only 4.8 W. This makes it a good fit for tanks in the 10–40 gallon range. For larger aquariums, consider pairing two units to broaden circulation and ensure thorough water movement.

• 135 GPH continuous flow for dependable circulation
• 2.5 ft lift helps push water to tank corners or filtration
• 4.8 W power draw supports energy-efficient operation
• Best suited for 10–40 gallon aquariums; two units can enhance larger tanks

Aeration and Oxygenation

Includes air tubing and an integrated venturi to boost oxygen transfer in the water. The added aeration works in harmony with your filtration, offering a gentle bubble supply that supports a healthy, clean environment without excessive noise.

• Air tubing and venturi for increased dissolved oxygen
• Fits standard aeration setups with simple connections
• Easy to connect and adjust for your tank layout

Movement, Heating, and Tank Health

Moving water creates a natural current that helps fish swim against flow and aids in transporting waste toward the filter. The circulation also assists in distributing heat from a heater more evenly, reducing cold spots and helping maintain consistent temperatures across the tank.

• Promotes debris movement toward filtration
• Helps heater heat distribute more evenly
• Reduces stagnant zones for a healthier tank

Installation Tips

For optimal results, place one unit at the back of the tank, on one side, facing inward. In larger tanks, position two units on opposite sides to balance flow and aeration across the water column.

Safety and reliability: fully submersible with an epoxy-sealed motor, designed to withstand underwater use and testing. Real-world results vary with tank setup and load, but many aquariums benefit from improved circulation and oxygenation.
