Collection: Fish Pumps & Aeration Accessories

Keeping aquarium water moving and oxygenated is the quiet work behind a healthy tank, and this range covers the gear that does it. Whether you run a nano tank or a big planted setup, aeration supports your fish, live plants and the beneficial bacteria in your filter.

• Air pumps — single, dual and multi-outlet, plus quiet and battery backup options
• Air stones and diffusers — bars, balls, cylinders and flexible strips
• Powerheads for water circulation, airline tubing, control valves and connectors
• Aquarium thermometers, glass and digital

Match pump output to your tank volume, and add a check valve to stop back-siphoning.
