The Koi Air pumps are very large and designed for use primarily in Koi ponds or very large ponds, which may be heavily stocked and have a high oxygen requirement. The large motor will produce more noise than smaller air pumps. If the noise level is unacceptable, housing the unit inside a brick outbuilding, such as a garage, rather than a shed, may be preferable.
In purchasing the pump, it is expected that most of the outlets will be utilised. If you only require one or two outlets, we would suggest that our Pond Oxygenator Kits may be more suitable for your requirements.
