Effective Aquarium Aeration

Oxygen is essential for aquarium fish and the beneficial bacteria responsible for biological filtration.

The Fluval 101 Air Pump supplies air to compatible aquarium aeration accessories, helping create bubbles and water movement.

As bubbles rise through the aquarium, they encourage surface agitation, supporting the exchange of oxygen and other gases between the water and atmosphere.

Supports Aquarium Water Circulation

Good water movement helps reduce stagnant areas and supports more consistent conditions throughout the aquarium.

When connected to a suitable air stone or diffuser, the Fluval 101 helps maintain gentle circulation and aeration.

Suitable for Air-Driven Aquarium Equipment

The Fluval 101 can be used with compatible aquarium aeration accessories, including:

• Aquarium air stones
• Air diffusers
• Air-operated aquarium decorations
• Compatible air-driven sponge filters
• Suitable aquarium airline tubing

Important: Airline tubing, air stones and other accessories are not included with this listing.

Installation Guidance

1. Position the air pump on a stable, dry surface away from aquarium water.
2. Connect suitable airline tubing to the pump outlet.
3. Attach a compatible air stone, diffuser or air-driven accessory.
4. Position the accessory in the aquarium.
5. Install a suitable non-return valve where required to prevent water flowing back towards the pump.
6. Connect the pump to an appropriate electrical supply.
7. Check that air is flowing correctly through the connected equipment.

Important: If the air pump is positioned below the aquarium water level, a suitable non-return valve is recommended to help prevent back-siphoning.
