We have a great selection of pond air pumps available at A19 Koi from brands such as Evolution Aqua, Superfish & Kockney Koi/Yamitsu. Pond air pumps are great for agitating the surface water of a pond which increases the capacity for gases to exchange and subsequently add more oxygen into the pond. This is especially important in densely stocked ponds or in summer months when oxygen levels within a pond can drop significantly. Pond air pumps are also essential for creating movement in moving beds and maintaining oxygen levels in biological filters. Don’t forget to check out our pond air accessories pages for those additional pond equipment items.
