To ensure the well-being of fish and plants in garden ponds and aquariums, proper aeration is essential. The right aeration keeps the water in motion, enriches it with oxygen, and promotes the development of beneficial bacteria. This important process can be hindered, especially at warm temperatures. When ponds or aquariums heat up, oxygen deficiency occurs. This leads to an imbalance in the water, preventing fish from receiving enough oxygen to thrive optimally. The lack of oxygen also results in the formation of harmful bacteria and algae. Not only high temperatures are detrimental, but also cold weather. Without aeration, a garden pond would freeze in winter, causing the pond inhabitants to be unable to breathe due to the lack of water movement. With aeration, the water remains in motion, preventing it from freezing completely. Therefore, the use of an aeration system is extremely important.

The quiet SunSun electromagnetic aquarium air pump HJB−120 takes on this crucial task of aeration. It operates with a pumping capacity of up to 120 liters per minute while consuming 80 watts of power. The pump is suitable for both freshwater and saltwater aquariums.

The pump's housing is made from a high-quality aluminum alloy. Thanks to its streamlined design, heat dissipation is more effective than with conventional pumps. This air pump is powered by an electric magnet motor and provides a constant aeration of the water.

For the air pump to run smoothly and efficiently for a long time, it is important that it is installed above the water level. Otherwise, water would flow back and not provide the necessary aeration. Alternatively, the electromagnetic air pump can be combined with a check valve.
