The Single Stick Diffuser Plate Assembly is a replacement diffuser designed for compact koi pond aeration systems. It delivers consistent oxygen release while maintaining a small footprint that works well in tighter pond layouts.

Built for straightforward installation, the plate includes a 3/8" barbed fitting that connects directly to standard 3/8" weighted airline. This makes it easy to restore proper aeration performance when replacing worn or damaged diffuser components.

Why Choose the Single Stick Diffuser Plate Assembly?

  • Targeted Aeration: Single diffuser stick provides focused oxygen delivery.
  • Compact Size: Ideal for smaller koi ponds and confined spaces.
  • Direct Fit: Designed specifically for the KoiAir Mini Aeration System.
  • Simple Connection: 3/8" barbed fitting connects easily to weighted airline.
  • Reliable Performance: Helps maintain steady aeration and water movement.

PRO TIP

When replacing a diffuser plate, inspect the airline for cracks or stiffness at the same time. Replacing worn airline sections can improve airflow and extend the life of the new diffuser.
