JBL - ProSilent Aeras Micro Plus L - Ultra Large Air Diffuser - 270mm

At night, an air pump with an air distributor makes sense for an aquarium, because plants do not produce oxygen without light and use themselves. In sparsely planted aquariums, an air pump provides the necessary water circulation through the diffuser. In a plant-rich aquarium, the air pump delivers oxygen to the aquarium at night since the large number of plants can reduce the oxygen content to problematic levels. In case of illness, the air pump increases the oxygen content of the water. This is necessary for many drugs.
