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 depletion occurs. This disrupts the water balance, and fish do not receive enough oxygen to thrive optimally. Oxygen deficiency also leads to the formation of harmful bacteria and algae. Not only do excessively warm temperatures pose a threat, but cold weather can also be detrimental. Without aeration, a garden pond would freeze in winter, preventing its inhabitants from breathing 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 vital 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. Its streamlined design allows for more effective heat dissipation compared to conventional pumps. This air pump is powered by an electric magnetic motor, providing a constant aeration of the water.

For long-lasting and trouble-free operation of the air pump, it is important that it is installed above the water level. Otherwise, water would flow backward, failing to provide the necessary aeration. Alternatively, the electromagnetic air pump can be combined with a check valve.
