Some recommended ways to aerate include:
• Aerators add oxygen to the pond using a special pump. The warmer the water, the more oxygen is needed.
• Spitters are small statues that spit or pour a stream of water into the pond. They are usually placed on or near the edge of the pond.
• Nozzle kits offer you a variety of water displays which you can adjust to varying heights depending on the power of your pump.
• Waterfalls not only help to circulate the water, they help oxygenate the water as well.
