Blagdon Koi Air Pond Oxygenator 3600 with a robust rubber diaphragm, this koi aeration system is durable and easy to replace when needed. Specifically designed for larger ponds, it has the ability to pump to a depth of several metres and encourages pond and fish health as aeration is essential for a healthy pond.

Use of an air pump will dramatically increase the level of oxygen in the pond and reduce carbon dioxide levels, thus aiding in preventing the pond from stagnating by injecting air into the water.
