Proper aeration in ponds or aquariums allows fish and plant life to thrive optimally. The oxygen keeps the water in the pond or aquarium in motion, promoting the development of beneficial bacteria.

During warm temperatures, ponds often experience oxygen deficiency, making aeration extremely important. In winter, using an aeration system prevents the pond from freezing.

Additional aeration of an aquarium is particularly recommended during disease treatment, as increased oxygen consumption is expected, and the current helps distribute the medication in the water. If the sun shines on the aquarium for several hours a day, using an aeration pump is advisable to prevent the water from heating up.

The quiet SunSun CT-402 pond and aquarium aerator pump impresses with a pumping capacity of 2 times 2.8 liters per minute, with a power consumption of only 4 watts.

The aerator pump is equipped with vibration-dampening rubber feet, which prevent the pump from "walking." The robust diaphragm pump is also characterized by its durability.
