Product information

Description

The Hagen Flat Aeration Stone 25 cm is a porous diffuser designed to introduce air into aquatic environments, producing a broad field of fine bubbles to improve oxygenation and support water circulation. Its flat, disc-shaped form provides an even distribution of airflow across a wide area, making it suitable for use in aquariums, garden ponds, and filtration systems that accept standard airline tubing and air pumps.

Advantages

The flat construction promotes uniform bubble output and reduces concentrated upwelling, which helps maintain gentle water movement and steady oxygen transfer. Made from durable, porous material, the aeration stone resists clogging when used with properly filtered air and is compatible with common aquarium airlines. Its large 25 cm diameter provides greater contact area between air and water compared to small stones, enabling improved diffusion and enhanced gas exchange without increasing noise or energy consumption.

Suitable for

  • Aquariums requiring increased oxygenation and gentle circulation
  • Garden ponds and outdoor water features for improved aeration
  • Filtration systems and sump tanks where broad bubble distribution is needed
  • Biological filtration setups that benefit from enhanced gas exchange

Key specifications

  • Shape: flat, disc-style aeration stone
  • Diameter: 25 cm
  • Material: porous mineral or ceramic composite (porous diffuser material)
  • Connection: compatible with standard airline tubing and typical aquarium air pumps
  • Function: produces fine bubbles for oxygenation and circulation

How to use

Attach an appropriate length of airline tubing from an air pump to the stone's inlet, ensuring a secure fit to prevent air leaks. Position the aeration stone on the bottom of the aquarium, pond, or filtration chamber, taking care that it rests flat to distribute bubbles evenly. Use an air pump with sufficient output for the 25 cm diffuser to create a fine, even stream of bubbles; if necessary, install a valve or air flow regulator to adjust bubble size and flow rate. Periodically inspect the stone and air lines for debris or reduced output and clean according to recommended maintenance procedures.

Usage recommendations

For consistent performance, use a pump with stable, oil-free output and include an inline check valve to prevent backflow. If the bubble pattern becomes coarse or flow drops, disconnect and soak the stone in clean water and gently scrub with a soft brush; avoid strong chemicals. In pond or outdoor installations, combine the stone with pre-filtration and routine maintenance to reduce clogging from organic matter.
