At Heathland Fountains and Aerators, we specialise in supplying and installing diffused aeration systems for ponds and lakes across the UK. Designed to deliver oxygen directly to the bottom of your pond, diffused aeration is one of the most effective ways to improve water quality, circulation, and overall pond health.
Unlike surface aerators, which oxygenate water from above, diffused aeration systems use an air compressor on the shore to pump air through weighted tubing down to diffusers placed on the pond bed. These diffusers release fine bubbles that rise to the surface, carrying oxygen and circulating water from the bottom up.This process ensures that oxygen is distributed evenly throughout the pond, even in deeper areas where surface aerators may not reach.
One of the biggest challenges in un-aerated ponds is thermal stratification. During warmer months, pond water naturally separates into layers:
Without circulation, oxygen cannot move between these layers. The bottom of the pond becomes oxygen-depleted, causing:
By continuously circulating water from the bottom up, mixing the water coloumn, diffused aeration breaks down thermal stratification, ensuring consistent oxygen levels and water temperature throughout the pond. This creates a balanced environment that supports healthier aquatic life and reduces water quality issues.
Installing a diffused aeration system provides a range of long-term benefits:
Diffused aeration systems are especially effective for larger or deeper ponds, where surface aerators cannot move enough water. They provide complete circulation from the bottom up, ensuring the entire pond remains clear, balanced, and healthy.
At Heathland Fountains and Aerators, we don’t just sell aeration systems—we provide a complete service, including:
Our diffused aeration systems are built to last, delivering reliable performance for many years with proper care.
If your pond suffers from poor water clarity, algae blooms, or unhealthy fish, a diffused pond aeration system could be the perfect solution.
