  • Reduces algae blooms and deters weed growth
  • Eliminates pond odors by venting off harmful gases
  • Reduces fish kill during hot and cold weather by dissolving increased levels of oxygen in the water when the fish need it most
  • Enhances the benefits of  Nature’s Pond Conditioner

Bottom-Up Aeration Windmills

  • Eco-friendly - no electricity required, powered by the wind!
