Air skimmer

Types of air skimmers

An air skimmer is a device that helps remove organic waste from the surface of the water. The organic waste can be in the form of leaves, dust, or any other debris that can affect the health of the aquarium. The surface water mostly has a high concentration of organic waste, which can be harmful if it is left to decompose.

With an air skimmer, the organic waste on the surface pulls in the air bubbles, and the bubbles rise to the top. Once they rise to the top, they can trap the debris and any other waste present on the water's surface. Most air skimmers have a collection cup that collects the organic waste removed from the water.

While air skimmers operate on a similar principle, they come in different types. The different types include:

• In-aquarium skimmers: These skimmers are usually placed inside the aquarium. They are suitable for smaller aquariums or those with limited space outside the tank. In-aquarium skimmers are further divided into two: needle-wheel and venturi skimmers. Needle-wheel skimmers have a wheel made of needles that spin when air is pumped into the aquarium. The spinning needles break the air into tiny bubbles. The tiny bubbles rise quickly, and the skimmer can trap more waste. On the other hand, venturi skimmers use a venturi effect to create bubbles. The venturi effect happens when air is pulled into the water at the inlet of the skimmer. The venturi skimmer creates fine bubbles, and as they rise, they trap more waste.
• Hang-on-back (HOB) skimmers: These skimmers hang on the back of the aquarium. They are popular because they are easy to install and maintain. They have a robust air pump that continuously pushes air into the skimmer. The HOB protein skimmer also has a collection cup that needs periodic cleaning.
• External protein skimmers: As the name suggests, these skimmers are placed outside the aquarium. They are suitable for larger aquariums. The external protein skimmer is more powerful than the in-aquarium and HOB skimmers. They have multiple chambers that allow the bubbles to stay longer. During this time, the bubbles can trap more organic waste. An external protein skimmer can remove up to 90% of the organic waste in the aquarium. They also come with adjustable knobs that help users set the skimmer's efficiency.
