The Astro Power Head is a submersible pump for aquarium use, driving water circulation, powering filtration and feeding returns, fountains and other water features. Still water is what lets waste settle and oxygen levels drop, so a powerhead does quiet, unglamorous work that keeps the whole tank healthier.

Key Features

• Fully submersible, for use inside the aquarium.
• Drives circulation, filtration and water feature returns.
• Threaded outlet for standard aquarium hose.
• Suction cup base for stable mounting on glass.
• Quiet running, suitable for display tanks in living spaces.

How to Use

Mount fully below the water line using the suction cups, positioned so the outflow moves water across the tank rather than straight into the substrate. Clean the impeller and intake grille periodically, since a blocked intake is the usual cause of a pump losing output or running hot. Never run the pump dry.

Safety

• Disconnect from the mains before removing the pump from the tank or servicing it.
• The pump must remain fully submerged while running.
• For indoor aquarium use only.
