How to choose a fish tank air pump?
There is a thumb rule to know if an air pump is suitable for your tank size or not. This is to choose one that features a flow rate equal to your aquarium volume. For example, a 50 gallon fish tank will need an air pump with a flow rate of 50 gallons per hour (GPH). However, this rule may vary based on your needs as well as the types and number of fish in your aquarium.
If you need an air pump to run your filters, choosing the right one rated for your tank size. An air pump with higher flow rate you will need if you have more things (filters, ornaments, large air stones…) as well as more resistance to push air through. Remember that too much alterations in the habitat of fish and they simply die! Therefore, to guarantee a good filtration and water recycling ability, a water pump or fish tank filter with a good flow rate should be on your buying list.
If your tank is too deep (over 18 – 20 inches in height) that mean the air pump you choose must be one designed to push air far below the water surface. Remember to check the durability, noise of operation and the service offered for the air pump before buying one. Following are some best options for you.

Benefits of fish tank aerators
To increase the aeration for your fish tank
When people bring into their homes certain species that they want to take care, it is very advisable to copy or imitate the original habitat of that certain organism. This is important because by doing so, you will make it easier for these organisms to cope and adapt easily to their new environment. This can be applied greatly to the fish that you put inside an aquarium. Copying their habitat can be achieved easily through the use of the right equipment such as aquarium filters, LED lighting, heaters, aerators…
Contrary to the popular belief that a fish tank air pump ‘supplies’ oxygen, the air pump actually promotes the dissolved oxygen. The increased dissolved oxygen means better and efficient gas exchange and minimizing of the harmful effects of other dissolved gases like ammonia. Ever wondered, that the oceans actually don’t have a huge air pump. Aeration is provided due to the super – sized surface area and the movements of the marine life in it.
The surface area inside the tank is obviously not as large as the surface area of other bodies of water so it also means that there is not enough oxygen circulating inside the aquarium. The benefits that aerators bring come into this picture. People use these aerators to help produce more oxygen for the fish inside the aquarium. This is really very helpful because it duplicates the original habitat of the fish to the highest possible level. As a result, fish easily feel that they are not far away from their original home.
To operate some aquarium filter types
The sponge filter in fry tank powered by an air pump
Some aquarium filter types such as undergravel filters, corner (box) filters, sponge filters and some types of protein skimmers need to be powered by aquarium air pumps. When these filters are working, the air is pushed from the air pumps to the filters and then it escapes out of the water that makes a power to keep the filters working.
In the filters use air pumps as their main power to operate, the air increases the dissolved oxygen content not only for the fish but also for the nitrification bacteria to build up and best perform biological filtration that keep the water clean and safe for fish.
To create a dynamic look with action ornaments
Using air pumps to create a dynamic look when used with such items as bubbling air stones with colorful LED lighting or to operate other aquarium action ornaments. The disturbances in the flow and agitation in the water helps operate some action decorations such as skeleton, spinning wheels… and make them look alive.
You can use some air pump accessories such as airline tubes and T-connectors to operate many action ornaments with a same good flow rate air pump.

Is an air pump necessary for fish tank?
Whether you really need a fish tank air pump is dependent on the fish you plan to keep in. Therefore, the answer to the question is a Yes or even a No, sometimes. For the large fish tank with small amounts of fish, you don’t need any air pump. Otherwise, for the small fish tank at home, an air pump is very much needed if your fish are high aeration need.
For large tanks enclosed though, the fish tank air pump is needed and is a requisite for ensuring that the fish live well! The huge closed fish tanks open for public exhibition are actually fitted with high performance, high capacity air pumps which provide optimum oxygen to the aquatic life underneath.
Bigger fish like the tiger, etc may require a fish tank air pump especially if the fish population density is high. Higher the number of fish, more rapid is the oxygen depletion in the water. Therefore an optimum ratio of fish should be maintained along with the functional, decorative items in the tank.
For Goldfish or Koi fish, too much of dissolved oxygen in the water can be detrimental for them. But keeping in mind, the amount of waste generated by a single goldfish, it is imperative to use one fish tank air pump. These are very sensitive creatures and respond to the even minutest changes in the water.
