There are three models of this EHEIM air pump available, offering pump outlets of 100 (single outlet), 200 (2 x 100), and 400 (2 x 200) l/h. The smallest model features one individually adjustable air outlet, while the two larger models each have two. Each pump comes with one or two EHEIM diffusors. You can regulate the air flow at each outlet on the pump and also on each diffusor, allowing you to create your own unique bubble effect. The pump is designed with vibration - dampening rubber edgings, which ensure quiet operation and keep the pump stable. It won't move around. Additionally, you can hang it vertically on the aquarium glass using the provided hook. The EHEIM air pump has many advantages. There are 3 models suitable for all common aquarium sizes. It operates very quietly and has a long service life with top - notch quality. You can adjust the airflow at each air outlet on the device, and further fine - tune the air flow and bubble effect using the diffusor. Each pump is fully equipped with diffusors (air pump 100 comes with 1x, air pump 200 and 400 come with 2x each) and airline (air pump 100 has 1 m, air pump 200 and 400 have 2 m each). Diffusors are also available as separate accessories. The rubber suction pads help dampen vibration, and the hook enables vertical hanging.
Using the EHEIM air pump is easy. First, choose the right model according to your aquarium size. If you have a smaller aquarium, the 100 l/h model might be a good fit; for larger ones, go for the 200 or 400 l/h models. Connect the included airline to the air outlets on the pump and the diffusors. Then place the diffusors inside the aquarium. You can adjust the air flow at each outlet on the pump and on the diffusors to get your desired bubble effect. To ensure quiet operation, make sure the pump is placed on a flat surface and the vibration - dampening rubber edgings are in good condition. If you want, you can use the hook to hang the pump vertically on the aquarium glass. When it comes to maintenance, regularly check the rubber suction pads for wear and tear. If they're not sticking well, replace them. Also, keep an eye on the diffusors. If they get clogged, you can clean them with water. This will help keep your air pump working smoothly and ensure a long service life.
