Keep your pond healthy and well oxygenated
Fish take oxygen from the water, and a pond air pump is a simple way to keep the oxygen levels up. Paired with the right airline and air stones, you will have the perfect aeration set-up.
Do I need an air pump for my garden pond?
Oxygen levels in a pond fall during warm weather, as well as with the growth of blanketweed, waste build-up, and even some medications. An air pump pushes air through an airline to an air stone or diffuser, creating fine bubbles that increase oxygen transfer and keep water circulating. Air pumps help most in ponds with koi or heavy stocking, in summer when oxygen naturally drops, in ponds with filters that benefit from extra circulation, and through the winter months to prevent stagnation. A fountain or waterfall adds some aeration, but many keepers still add an air pump in hot weather or in a busy pond.
What are the main types of pond air pump and accessory?
- Pond Air Pumps and Aerators: the pumps themselves, in three types: Mains-Powered, Solar-Powered, and Aerator Pumps
- Pond Airline and Accessories: the parts that complete the set-up, in three types: Airline Hose, Air Stones, and Connectors
What should I look for when choosing an air pump?
Choose air output to suit your stocking levels: the more fish you keep, the more air you need. Check the number of outlets if you plan to run several air stones, and compare output in the same unit, because some pumps quote litres per minute and others litres per hour. Energy use matters because air pumps usually run all the time, and quieter motors are more pleasant near a patio. Finally, check whether the pump is weatherproof or needs a cover. For example, Swell Maxi pumps must be covered from the elements, while the Swell Pond Air Pump is weatherproof.
What do I need to set up an air pump?
Most set-ups need an air pump, some airline, and one or more air stones or diffusers. A non-return valve and a manifold or connectors help if you want to run more than one stone. Air pumps work alongside your water pump and filter, not in place of them, so see our pond pumps and pond filters, or try our pond pump calculator to size your water pump from your pond dimensions.
