Description
The 6″ Dome Air Stone is a durable aeration diffuser designed to provide excellent oxygen distribution and water movement throughout pond and aquatic systems.
Its dome-shaped design allows air to be dispersed evenly across the diffuser surface, producing a consistent stream of fine bubbles that maximise oxygen transfer and improve circulation.
The increased oxygen levels help support fish health, beneficial bacteria growth and biological filtration performance, making the diffuser ideal for koi ponds, garden ponds, quarantine systems, moving bed filters and aquaculture applications.
The robust construction and reliable performance make it suitable for both hobbyist and professional pond installations.
