Air Pumps aerate the water and keep your fish alive. They are one of the most important parts of an Aquaponics system. We recommend a backup aeration system to keep your fish alive in the event of a power cut. Our range of air pumps are suitable for use in Aquaponics systems and include weather proof air pumps, 12V DC air pumps and a 240V AC air pump with battery backup (suitable for aerating your water even if the power goes out). See our range of air pumps below.
