Types of Air Pumps for Home Aquariums: What You Need to Know

One of the important pieces of equipment that you will want to consider investing in for your aquarium is an air pump. Air pumps serve several purposes. They can help circulate the aquarium’s water to keep it from stagnating as well as help with the water’s dispersal of carbon dioxide and intake of oxygen. They can also be divided into two main groups. Here’s a quick overview of each one:

Motor-Driven Cylinder Air Pumps

Based on my experience, motor-driven cylinder air pumps tend to be more powerful than vibrator pumps. They also tend to break down less and are often easier to repair. They do, however, require routine maintenance. Most require periodic oiling of the flywheel and adjustments to flywheel belt. Of course, if it gets too worn down, the flywheel belt will need to be replaced. I’ve also had to clean them periodically with a specialized cleaner to remove built up gunk. It typically isn’t that hard to do. The method will vary based on the pump’s make and model. Most manufacturers will provide instructions on how to do it if you ask. Motorized, cylinder style, air pumps can cost over $200 or more a piece.

Vibration Air Pumps

Vibration air pumps operate on a diaphragm system and tend to provide minimal pressure. I have never had much luck with them. I found them to break down more often and require a specialist to repair. They also tend to make noise, which drives me crazy at night. I have found that you can lessen the incessant hum with a piece of foam or thick felt. However, it doesn’t seem to ever totally go away. On a positive note, they are very inexpensive to purchase and do not require routine maintenance. Prices for this style of air pump tend to start at $15.

Which One is Best?

What type of air pump you ultimately choose is really a matter of personal preference. It can also be determined by what kind of tank set-up you have. For example, if you go with a cylinder pump it could give off some heat after prolonged use. Therefore, you wouldn’t want to place it near something that is heat sensitive. You’ll always want to leave enough space around the pump so the air can circulate around it and help to reduce the potential for overheating. I also wouldn’t recommend placing a vibration air pump on a surface that would only intensify the unit’s natural noise making ability.
