  • Keep away from direct sun
  • Position above water level

Solar Panel Setup

  • Mount facing south - keep out of all shade
  • Use wall mount if provided
  • Ensure stable mounting
  • Adjust angle seasonally
  • Keep panel surface clean

Stone Placement

  • Position at mid-depth
  • Spread for even coverage
  • Secure tubing carefully
  • Avoid deepest areas
  • Check bubble distribution

Performance Tips

  • Angle panel for noise control
  • Regular stone cleaning
  • Monitor air flow strength
  • Check connections monthly

How Your Pond Aerator Works

Understanding the simple but effective operation of your aeration systems, with and without battery backup.

Basic Operation

  • Solar panel converts sunlight to electricity
  • Powers efficient diaphragm pump
  • Pump creates continuous air flow
  • Air stones diffuse oxygen into water
  • Creates vital water movement
  • Operation is reduced or paused in shaded locations, even during summer.

Solar-Only Systems

  • Direct sunlight operation
  • Strongest in peak daylight
  • Variable flow with light levels
  • No nighttime operation
  • Zero running costs
  • Will not run in shade or heavy cloud, regardless of season.

Battery-Backed Units

  • Daytime charging
  • Night-time operation possible
  • Consistent air flow
  • Weather-independent backup
  • Extended operating hours
  • Performance still depends on sunlight for recharging.

Oxygenation Process

  • Air bubbles rise through water
  • Oxygen transfers to water
  • Creates vertical water movement
  • Improves surface gas exchange
  • Prevents stagnant areas

System Benefits

  • Increases dissolved oxygen
  • Supports pond life
  • Reduces algae growth
  • Prevents stratification
  • Eco-friendly operation

Performance Factors

  • Available sunlight
  • Panel positioning
  • Stone/cylinder placement
  • Pond depth and size
  • Seasonal variations
  • Shaded panels mean reduced or no operation at any time of year.
