## Summary description

Hagen aeration stone in a trapezoid shape, size 10 x 1.8 cm, designed for aquarium air diffusion. This air stone produces fine bubbles for improved oxygenation and water circulation. Suitable for use with air pumps and airline tubing to enhance gas exchange in freshwater or marine tanks, beneficial for fish health, plants and biological filtration.

## Long description

Hagen Aeration Stone Trapezoid 10 x 1.8 cm is an aquarium air stone shaped as a trapezoid to provide even diffusion of air across a compact area. Made for use with standard air pumps and airline tubing, this aeration stone produces fine bubbles that enhance oxygen transfer and promote gentle water circulation. It is suitable for both freshwater and marine aquaria and can support fish respiration, plant health and efficient biological filtration by increasing surface gas exchange.
Advantages
The trapezoid design creates a broad, uniform bubble pattern while occupying minimal space, allowing placement along tank edges or under decorations. Fine bubble output increases dissolved oxygen levels more efficiently than coarse bubbling and reduces strong water currents that can stress small or delicate species. The durable material resists clogging under normal use and connects easily to typical airline tubing for straightforward setup.
Suitable for
Oxygenating freshwater community tanks
Enhancing gas exchange in planted aquaria
Supporting biological filtration in marine and reef systems
Providing gentle aeration for fry or delicate invertebrates
Key specifications
Shape: trapezoid
Dimensions: approximately 10 cm × 1.8 cm
Bubble type: fine-bubble diffusion
Compatibility: standard aquarium airline tubing and air pumps
Suitable water types: freshwater and marine
How to use
Attach the aeration stone to airline tubing connected to a suitable air pump, ensuring the pump’s output matches the stone’s resistance for optimal bubble size. Place the stone in the desired location within the aquarium—on the substrate, behind ornaments, or tucked along the rear glass—making sure it is fully submerged. Prime the airline and start the pump, then observe bubble pattern and adjust airflow with a valve or pump control to achieve the preferred diffusion and water movement.
Usage recommendations
For best performance, periodically inspect the aeration stone for mineral buildup or debris and gently clean it by soaking in dechlorinated water and using a soft brush or gentle backflow of air. Replace the stone if clogging cannot be removed or bubble output becomes uneven. Match the air pump capacity to the aquarium size and consider using a check valve to prevent water backflow into the pump.
