It is widely recognised that good aeration is essential for good pond water conditions and healthy fish.
 
Koi Air is a reliable way of supplying aeration to ponds and filters.
 
Koi Air pumps are specifically designed for use with larger ponds, where the ability to pump to several metres depth with many airstones is important.
