The PondSeries PS20 aeration system is designed to improve overall pond health by circulating oxygen from the bottom upward. By delivering air to bottom-mounted diffusers, the system creates rising columns of bubbles that move water vertically, helping eliminate thermal layering and stagnant zones.

Increased oxygen supports beneficial bacteria that naturally break down excess nutrients and organic waste. This process helps reduce muck accumulation, improve water clarity, and lower long-term maintenance needs, with visible improvements often seen within a single season.

Why Choose PondSeries PS20?

  • Effective Water Circulation: Bottom-up aeration disrupts thermoclines and improves whole-pond circulation.
  • Cleaner Pond Conditions: Increased oxygen supports natural bacteria that reduce nutrients and organic buildup.
  • Quiet, Powerful Compressor: 1/2 HP rocking piston compressor delivers up to 4.7 CFM with low noise and vibration.
  • Flexible Installation: Can be installed at the shoreline or up to 1/4 mile away with no power required at the pond.
  • Durable Composite Cabinet: Faux rock cabinet protects components from weather while blending into the landscape.
  • Low Maintenance Diffusers: Self-weighted membrane diffusers resist clogging and remain upright on the pond bottom.

System Components

  • SilentAir Rocking Piston Compressor: Built with SmartStart Technology to protect the compressor during pressurized restarts.
  • Composite Cabinet: ETL-certified housing with elevated base, ventilation fan, rain shroud, and dual air filtration.
  • Airflow Manifold: Two-port manifold with nickel-plated ball valves, pressure gauge, and pressure relief valve.
  • ProAir 4 Weighted Diffusers: Two diffuser plates with integrated check valves and maintenance-free sled design.
  • Weighted Airline: Optional 3/8" self-weighted airline that is kink-free and fish hook resistant.

PRO TIP

If your pond has never been aerated or has heavy muck buildup, start the system gradually by running it for short periods and increasing runtime over several days. This helps the pond ecosystem adjust safely to higher oxygen levels.
