Aquarium air pumps are simple machines that are very effective in the fish industry. However, most aquarium air pumps are noisy and can be very annoying. Which is why you need to find the quietest aquarium air pump that is suitable for your specific fish tank.
Generally speaking, aquarium air pumps work by displacing air from the atmosphere into the aquarium. As the air is forced into the water it creates bubbles that remove carbon dioxide from the water while oxygenating the water.
Aquarium air pumps come in various designs. Additionally, there are several brands available in the market today at affordable prices.
Having in mind that most aquarium air pumps can be very noisy and annoying. We reviewed several aquarium air pumps, to find out which is the quietest and most effective.
Do you need an aquarium air pump?
Aquarium air pumps are important equipment that you should consider having in your fish tank for many reasons.
First, aquarium air pumps deliver breathable dissolved oxygen into your fish tank for fish and other aquatic animals and plants.
Secondly, aquarium air pumps help to even out gas exchange within the aquarium through surface agitation. Surface agitation allows oxygen that is on the surface of the water to get in and lets the carbon dioxide that is inside the water to come out.
The other reason that you may need an aquarium air pump, is if you have sponge filters. Sponge filters need an aquarium air pump in order to be able to run and filter the aquarium water.
Lastly, aquarium air pumps make the aquarium look awesome. Aquarium air pumps give you the option to install several aquarium decorations that make the aquarium pleasing to look at.
Factors to consider when selecting an aquarium air pump
- Size of the air pump – the size of the air pump is rated using the flow rate per aquarium size in gallons. Ensure that you match the size of the aquarium to the rating of the aquarium air pump.
- Presence of tank decorations, toys or air stones – If you intend to use tank decorations together with the air pump, choose an air pump that is rated for a bigger aquarium tank. This is because aquarium toys, decorations or air stones require additional flow capacity.
- Type of sponge filter present – choose an air pump that matches the type of sponge filter that you have.
- Number of sponge filters present – If you have several sponge filters running in your aquarium, chose an aquarium air pump that is capable of running multiple filters.
- Your budget – chose an aquarium air pump that matches your budget while being effective.
