Aeration Stone (Trapezoid) Hagen KAMIEŃ NAPOWIETRZAJĄCY 30.5 x 2 cm

The Hagen Trapezoid Aeration Stone (30.5 x 2 cm) is a porous diffuser designed for use in aquariums and garden ponds. Connected to an air pump, the stone produces a steady stream of fine bubbles that increase oxygen dispersion, support biological filtration, and promote water circulation. Its elongated trapezoid shape provides consistent aeration across a wider area, helping to reduce stagnant zones and improve gas exchange in freshwater environments.

Advantages

The trapezoid aeration stone delivers uniform fine-bubble output for efficient oxygen transfer while minimizing oversized bubbles. Its elongated form allows placement along filters, substrate edges, or pond bottoms to create even water movement. Constructed from durable porous material, the stone resists clogging under normal aquarium conditions and is compatible with standard airline tubing and air pumps. Installation and routine maintenance are straightforward, and the device operates quietly when paired with an appropriately sized pump.

Suitable for

• Aquariums requiring improved oxygenation and circulation
• Garden ponds and water features to reduce dead zones
• Biological filter support in freshwater setups
• Environments where fine bubble diffusion is needed for gas exchange

Key specifications

• Shape: Trapezoid diffuser for linear coverage
• Dimensions: approximately 30.5 cm length x 2 cm width
• Material: porous aeration stone material suitable for continuous water contact
• Connection: designed for use with standard airline tubing and air pumps
• Bubble type: fine-bubble diffusion for efficient oxygen transfer

How to use

Attach the aeration stone to an air pump using suitable airline tubing and place it on the aquarium or pond bottom in the area that requires improved circulation. For larger tanks or ponds, position the stone along the length of the filter intake or in the area where water tends to stagnate. Start with a moderate pump output and adjust airflow to achieve a steady stream of fine bubbles without causing excessive surface disturbance. Periodically check the stone for reduced bubble output and clean gently if needed by soaking or rinsing in dechlorinated water.

Usage recommendations

Use an air pump sized appropriately for the aquarium or pond volume to maintain consistent fine-bubble output. Avoid harsh mechanical cleaning or strong chemicals; if clogging occurs, soak the stone in warm dechlorinated water and gently brush with a soft brush. Position the stone to support filter flow patterns and oxygenate areas with low circulation for best results.
