Frequently Asked Questions

Here are answers to your most frequently asked questions regarding aquarium air pumps.

How Long Do Aquarium Air Pumps Last?

An aquarium air pump can easily last for over ten years. Many veteran aquarists have had their air pumps for over 20 years as well. One thing to remember is that if your air pump is used in a saltwater tank, its lifespan will be significantly reduced compared to that of freshwater.

Why Is My Aquarium Air Pump Not Working?

The most probable reason for your air pump not working can be that the filter’s airlines are unplugged or damaged. Another possibility is that the mechanical filter of your aquarium is not operating correctly.

Cleaning your filter is important for maintaining a constant airflow. Other causes of air pump failure can include a damaged rubber bladder, improper air pump location, and defective tubing.

Why Is My Aquarium Air Pump So Loud?

A worn diaphragm is the most likely cause of a loud air pump. Other reasons include forcing it to pump air into a larger tank, which creates more pressure and/or gradually moves the diaphragm, creating higher vibration in the pump. All of these factors can make it loud and noisy. However, good care and a few improvements can help it become quieter.

How Do I Know If My Fish Tank Has Too Much Oxygen?

If your tank contains a lot of bubbles, it might be an indication that you have too much oxygen in it. To be sure of the air level in the tank, you will have to use an oxygen testing kit. 8 mg/l or higher is recommended for freshwater aquariums and ponds. At least 7 mg/l is advisable for saltwater tanks.
