Tornado AirStorm Weighted Bubble Curtains

Low resistance weighted bubble curtains for pond aeration and oxygenation

Tornado AirStorm Weighted Bubble Curtains are pond air diffusers designed to create a long, even line of bubbles rather than a single concentrated bubble point. They are useful where you want a visible curtain of aeration across part of a pond, filter bay, holding tank or quarantine system, while also helping to increase dissolved oxygen and improve water movement.

The weighted design allows the bubble curtain to sit neatly on the pond floor without needing separate weights. This makes installation much tidier than trying to hold down loose airline or lightweight air stones. The low resistance membrane is designed to reduce unnecessary back pressure on the air pump, which is important because excessive restriction can reduce airflow and put extra strain on diaphragms or other wearable pump parts.

Key benefits

• Creates a long, even bubble curtain rather than a single bubble point
• Helps increase dissolved oxygen in ponds, koi ponds and holding systems
• Weighted design helps the diffuser stay in position on the pond floor
• Low resistance membrane helps reduce back pressure on the air pump
• Useful for improving water circulation and reducing stagnant areas
• Available in multiple lengths to suit different pond layouts
• Suitable for use with an air pump, manifold and correctly sized airline

Available sizes

• 300mm: compact bubble curtain for smaller ponds, tanks or targeted aeration areas
• 600mm: medium bubble curtain for general pond aeration and wider coverage
• 900mm: longer bubble curtain for larger ponds or broader oxygenation zones

Technical specifications

• Product type: Weighted pond bubble curtain / air diffuser
• Available lengths: 300mm, 600mm and 900mm
• Airline connection: 8mm tail
• Installation: Weighted diffuser for placing on the pond floor or in a suitable filter/tank area
• Best use: Pond aeration, koi pond oxygenation, holding tanks, quarantine systems and improved water movement
• Air pump requirement: Use a suitable air pump and balance airflow through a manifold where multiple diffusers are installed

Choosing the right size

The 300mm version is best for smaller areas or more targeted aeration. The 600mm version is a good general-purpose choice for many ponds. The 900mm version provides the longest bubble line and is useful where you want broader coverage across a pond base or holding system. On larger installations, it is often better to use a suitable manifold so each air outlet can be adjusted rather than forcing all the airflow through one line.
