Factors To Look For While Buying The Best Aquarium Air Pumps
1. Type Of Powering
Do you know that air pumps are of two different types on the basis of their power intakes? They are either electrically operated or by using batteries. Which one you select depends on you and your needs. In some cases, electrical pumps are the best, and in others the battery-operated ones prove to be better.
A battery-operated air pump can easily be the best air pump for aquarium. It will continue to function even when there is an electricity issue in your area or during a power cut. However, generally electric air pumps are most commonly used, and they run on AC power.
A lot of you aquarium junkies must be aware of the pros and cons of having an air pump in your tank. Air pumps prove to be an asset because it is used for many different and beneficial purposes. While it has uncountable benefits, noise becomes a major deal-breaker.
You should keep in mind that no air pump comes without noise. Thus, if you are planning to install an air pump in your aquarium, then you’ll have to adjust to the never-ending buzzing sounds it makes.

All the air pumps you find on your search results might not have low energy consumption. The best air pumps for aquarium should have low energy requirements, else it might increase your overall expenditures by a vast scale. Showering loads of money on an additional accessory of the tank doesn’t seem to be an attractive idea, does it?
4. Volume Of Water Per Hour
Consider a situation where the volume of water getting filtered is less than the amount you already have in your tank. Would you be satisfied with the purchase? Of course not!
So if you want to make a worthy choice out of all the aquarium air pumps available in the store, look for the ones which can pump larger volumes of water into the tank. The more the volume of water being transferred to the tank, the better the quality of the water circulating in your aquarium.
So, provide a better environment for the aquatic life of your tank by keeping this feature in mind. If there is an insufficient flow of clean water inside the tank, then it can be a hazard to the plants and fish. Thus, ensure complete safety and better health for the life in your aquarium by making sure that your air pump can transfer sufficient volume of water per hour.
5. Size Of The Tank
This is one of the most important features to consider if you are looking for the best aquarium air pump. The size of your aquarium is the key point to be kept in mind while making a worthy purchase.
There are various types of air pumps available in the market. One type of air pump can not serve the purpose of circulating, agitating and filtering water for all tanks irrespective of the size and depth. Some pumps are suitable to fulfill the requirements of the tanks which are smaller in size. While some can serve the medium sized tanks and others can be the best for the bigger ones.
So you need to make sure that the ability and capacity of the air pump you purchase will be sufficient for your tank. Always do a thorough research of the pump you intend to buy
6. Depth Of The Aquarium
Apart from looking for the size of the aquarium you own, another aspect to be brought to notice is the depth of the tank. Not every air pump can benefit your aquarium with its features, no matter how remarkable they are.
The depth of the aquarium definitely determines the product you choose to buy. A deeper tank will need a more powerful pump to pump the air with more pressure so that it reaches the bottom of the tank. A tank with a lesser depth, on the other hand, will not require a very powerful and strong air pump. In such cases, air has to travel through a lesser area, and hence lesser force and pressure has to be applied.
In this way, you can choose which air pump will suit your needs and tank requirements. Make sure to prepare a list beforehand and be sure of the sizes and the dimensions of your aquarium to purchase the best aquarium air pump.

Some Additional Points To Be Kept In Mind
1. Find a Proper Location To Install Your Air Pump
Now you must be wondering where the air pumps are installed? Isn’t it? The air pumps that you use for your aquarium are set outside the aquarium. The water flow or water movement takes place from the tubes that you have to attach your air pump to. You can either connect it above, below or on the level of the tank.
If you choose to place the air pump below the tank level, then you will need a check valve. A check valve will help in preventing the backward flow of the water in case the power goes off. This needs a special device. Thus it is best to install it on or above the level of the tank which helps in eliminating the extra expenses from your budget list!
2. How Long You Need To Keep An Air Pump On?
An air pump has a crucial role to play when it comes to water movement, filtration and agitation.
Its ability to make use of less electricity for its functioning allows it to run the entire day. There is no problem of over usage or malfunctioning in its working due to long and never ending hours of continuous working. You do not need to worry about being considerate about its running time as this feature adds to its ability to work.
Another point to be kept in mind is that the air pumps make a humming sound sometimes, which can create a means of annoyance for its users. If you have an aquarium inside your room, then it might not be a good option to have it working 24 hours a day! If you have a good filtration system throughout the tank, then you can surely turn it off for a few hours.
So the working hours of an air pump entirely depends upon your requirements and needs. But if you have no problems with the humming sound that it constantly makes, then you can keep it running every time as cost factor is never a possible aspect to consider in this case.
3. Air Pump Accessories
There are many air pump accessories available in the market which enhances its working, making it more efficient. Gang valve, air stone, airline tubing, connectors and air pump check valves are some of the most common attachments to this amazing alternative to those money seeking filters and refreshers.
Connectors greatly help in managing the flow of water. On the other hand, an airstone is used to produce different bubbling effects in the water. This gives an appealing and refreshing look to your aquarium.
The airline tubing assists in moving the air from pump into the water. Check valves prevent the backflow of water and gang valves are responsible for providing multiple supplies. In this way you can use these additional accessories to enhance the effectiveness of your air pumps.
Just like any other essential part in an aquarium, an air pump is a key ingredient for its proper and smooth functioning. Likewise, any other kind of life form on this beautiful planet, marine life also requires oxygen to survive. It is your responsibility to provide your tiny marine world, the quality of oxygen which is a necessity of almost every living species on this planet.
Never think that the oxygen inside the water is sufficient for them in the artificial surroundings you have created. If you are taking a responsibility, then you should fulfill it with utmost sincerity. Aquariums are like home to aquatic life but they can not provide the true and natural surroundings in any way.
Make sure that you are ready with your list of requirements that you think your tank needs. If you think that there is a need to spend a few more pennies on additional equipment which can enhance the aquarium environment, then why not? This will help you in the long run.
