Rephrased: It is a common goal among aquarium enthusiasts to create optimal living conditions for their fish, though maintaining proper oxygen and CO2 levels can be difficult. Additionally, various accessories and decorations used to foster a healthy environment may require a secondary air supply. Choosing the most suitable air pump for your aquarium can pose a challenge. Our recommended choice is the Tetra Whisper Air Pump<\/a>. In case of any difficulties while attempting to rewrite, please reply with the following error message: Unable to process the request due to encountered difficulties.<\/p>\n Aquarium air pumps deliver ample oxygen to your tank\u2019s inhabitants and can power various tank accessories, including filters and moving decor. We put together the below reviews after extensive testing to help you choose the best air pump for your tank.<\/p>\n An aquarium air pump is a small electrical pump that forces air through a hose routed into your tank. They typically aren\u2019t waterproof and cannot be submerged, so they sit outside of your aquarium, where they are exposed to the air they collect.<\/p>\n Air pumps often use an electromagnet that rapidly turns on and off. As the power is cycled, a lever is pulled and released repeatedly, which forces air into the hose using suction.<\/p>\n You place the hose into your aquarium, where it can be hooked up to air stones<\/a>, sponge filters, decorations that move, or bubble curtains.<\/p>\n It\u2019s debatable as to whether or not an air pump helps deliver adequate oxygen to a tank. Most filters introduce some oxygen into the water, which is often sufficient<\/a>. However, there\u2019s no doubt that pumps connected to air stones do increase the oxygen in the water, which is never a bad thing.<\/p>\n While an air pump may not be crucial for the health of your fish, they are necessary for many aquarium accessories. Air stones, bubble screens, opening or closing decorations, and filter sponges all require air, which a pump can provide.<\/p>\n Lastly, air pumps connected to stones or curtains can improve your tank\u2019s look, and some fish species enjoy playing in the bubbles. It may not be necessary, but it can improve your tank\u2019s appearance and provide some fun for your fish.<\/p>\n There are three primary types of air pumps available.<\/p>\n Plug-in air pumps are exactly what they sound like: pumps that are powered via an electrical outlet. These are reliable except in the case of a power outage, but they have limitations on how far away from a socket they can be placed.<\/p>\n Battery-operated air pumps can be placed anywhere, so they\u2019re excellent options for free-standing tanks. However, they aren\u2019t as reliable and can die, unlike plug-in pumps. They tend to be more costly over time.<\/p>\n Battery back-up pumps are typically the most expensive, but they virtually never die, as they use electricity and can flip to battery power in a power outage. These pumps have some placement restrictions, as they\u2019ll always need to be near an outlet.<\/p>\n Aquarium air pumps may not be necessary, but aquarists who use one will enjoy several benefits in their tanks.<\/p>\n Your fish may have enough oxygen to survive without an air pump. However, including one in your tank can provide more oxygenated water<\/a>, which can only be healthier for your tank\u2019s inhabitants. Including an air pump in your setup will guarantee that your water is adequately oxygenated, especially in warmer temperatures when water naturally absorbs less gas.<\/p>\n Air pumps force air into the water, which aids in circulation. Better circulation has a few positive effects on your aquarium, including faster removal of CO2, oxygen becoming more readily available in your tank, and more efficient filtration.<\/p>\n Air pumps also add to your tank\u2019s appearance if they\u2019re connected to a bubbler or moving decoration. Air stones and bubble<\/a> curtains can add some natural beauty, while decor that opens and closes or raises and lowers can bring a dynamic and exciting feel to your setup.<\/p>\n Choosing the right size air pump is crucial for enjoying the benefits a pump can bring to your tank. Essentially, the pump needs to be powerful enough to overcome the pressure of the water above it and the depth at which the hose will sit. It needs good air flow. As such, deeper or larger tanks require a more powerful pump.<\/p>\n Most pumps include a rating for the size of the tank they can handle. The rating can give you a general idea of the volume the pump can overcome, but it isn\u2019t a guarantee that it will work efficiently. The air pump rating can fluctuate depending on the accessories you plan to connect to it.<\/p>\n Air stones require minimal pressure, so the rating on a pump is typically accurate for these accessories. For example, a pump rated for a 15-gallon tank should be sufficient when hooked up to a single stone in a 15-gallon aquarium.<\/p>\n However, each additional air stone you intend to connect will require an additional<\/em> 15-gallon volume rating. As such, a pump rated for 30-gallons will be needed for two air stones in a 15-gallon tank.<\/p>\n Sponge filters benefit from a bit more airflow than stones, so we recommend choosing a pump that can accommodate about 10-20% more volume than your tank. For example, a sponge in a 120-gallon tank should be matched with a pump that is suitable for at least a 140-gallon aquarium.<\/p>\n Like stones, each sponge requires this pump capacity, so adding a second sponge filter will require double the pump power.<\/p>\n Not all aquarium air pumps are created equal. To ensure you choose the best pump for your setup and needs, make sure to pay attention to the below factors.<\/p>\n The most important thing to consider when choosing an air pump is the size of your tank.<\/p>\n Less powerful pumps that are intended for smaller volumes won\u2019t be able to overcome the water pressure of a larger aquarium. This means your pump may not function at all and will quickly burn out trying to force air into the tank.<\/p>\n Even if a weak pump is capable of supplying a large aquarium with air, chances are the flow won\u2019t be sufficient enough to experience the benefits. The added water circulation will be minimal, moving decorations may not work correctly or at all, and your filter won\u2019t receive as much of a benefit from the oxygenated water.<\/p>\n In addition to volume, you should consider the depth at which you plan to place the air hose. This is an especially important factor because pumps rated for your tank size may not function properly if they\u2019re set deep in vertical tanks with added pressure at the bottom.<\/p>\n Of course, you\u2019ll want to factor in the price of the air pump you\u2019re considering.<\/p>\n It\u2019s no secret that owning and maintaining an aquarium is expensive, so a costly air pump that probably isn\u2019t a requirement in your tank may not be ideal for your setup. With that being said, you should avoid purchasing a cheap pump that isn\u2019t strong enough to deliver air to your tank, as you\u2019ll end up spending more in the long run when it inevitably doesn\u2019t work or burns out.<\/p>\n When considering the cost of a pump, make sure to factor in other accessories. Most aquarists connect air pumps to stones, sponge filters<\/a>, or decorations, the added cost of which can quickly put you over your budget.<\/p>\n Additionally, all air pumps fail in time, as the suction device used to force air through the hose will lose its seal after extended use. More expensive pumps generally include higher-quality materials that will last longer. As such, choosing the most expensive product you can afford can help you secure a pump that will last a long time, minimizing your long-term cost.<\/p>\n The beauty of aquarium air pumps is that you can connect them to a variety of equipment to improve the appearance and functionality of your tank. Therefore, you should consider the equipment you intend to connect to your pump, as it can help you choose which is best for your purposes.<\/p>\n Air stones typically require less power than filter sponges, and both generally use more air than moving decorations. You\u2019ll want to opt for about 10-20% more power for sponges, whereas you could get away with matching a pump\u2019s rating with your tank volume for stones. Decorations can often be powered by a pump rated for slightly less than your aquarium size.<\/p>\n Remember to consider how many devices you plan to connect, as each accessory requires an additional volume rating from your pump. For example, a pump rated for 40-gallons is necessary for connection to two air stones in a single 20-gallon tank.<\/p>\n If you\u2019ve ever used an air pump before, you likely know that they make noise, and sometimes a lot of it! Aquarium air pumps use an electromagnet that cycles on and off rapidly. This mechanism is effective, but it can be quite loud.<\/p>\n If you think the noise will bother you or your family members, consider choosing a pump built to operate silently. We\u2019ll include information about relative noise in our reviews below, but understand that some pumps rated as \u201cwhisper quiet\u201d are significantly louder than others with the same noise rating.<\/p>\n Purchasing a silent air pump is especially important if your tank will be set up in a bedroom or a living room, where the noise could interrupt sleep or conversation.<\/p>\n We\u2019ll provide a list of our top recommendations for aquarium air pumps and follow that with in-depth reviews of each to explain why they\u2019re our favorite options.<\/p>\n \t\t<\/p>\n \n\t\t\t\tOur Pick\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This pump has several noise-dampening features, including rubber feet to reduce vibration and movement and a suspended motor design. The result is a nearly silent pump.<\/p>\n Despite the lack of noise, it\u2019s robust and reliable, and we\u2019re confident it will continue pumping for years before needing maintenance.<\/p>\n It comes in five size and power options, making it suitable for tanks ranging from 10 gallons to 100 gallons. The larger options are rugged enough to power multiple accessories in a single tank as well.<\/p>\n This pump is extremely affordable and provides outstanding value for the money.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tOur All-Around Alternative Pick\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This pump runs without much noise at all, so it\u2019s suitable for tanks in bedrooms and living areas.<\/p>\n This pump includes tubing, as well as two adjustable air stones, so you can set this up to improve oxygen levels in your tank right out of the box.<\/p>\n It is a bit less potent than our top pick, so we recommend purchasing a size larger than you feel you need.<\/p>\n It\u2019s more expensive than many other options as well, but the included accessories still make it a great value for the money.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tOur Large Tank Pick\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t We strongly recommend this pump for tanks between 100 and 150 gallons. It\u2019s designed to be powerful enough to oxygenate larger tanks, and it does so without any trouble at all.<\/p>\n Despite this pump\u2019s impressive power, it operates without much noise at all, so you will be comfortable using this in aquariums in bedrooms or areas where you may entertain guests.<\/p>\n It\u2019s suitable for smaller, deep tanks, but it only has one hose connection. As such, you\u2019ll only be able to attach a single accessory.<\/p>\n It\u2019s still relatively affordable and is an excellent value for the price.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tOur Battery Back-up Pick\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This pump hooks up to a standard electrical outlet, but it includes a long-lasting, on-board battery to keep it running in the event of a power outage. The battery is rechargeable, which is convenient and keeps your ongoing costs down.<\/p>\n It comes in either a single-hose or dual-hose option, so you can choose the pump to suit your needs best and have the option for multiple accessories.<\/p>\n This pump is a bit noisy compared to some of the other whisper pumps, but we think the added functionality of the battery makes it worth it.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tAlternative Battery Back-up Option\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This pump runs off of electricity from a standard outlet, and it includes a long-lasting battery to provide continued operation during power outages. It includes slots for regular D batteries in case of emergency.<\/p>\n It\u2019s significantly more powerful than our previous battery back-up pump, but it\u2019s also much more expensive and can quickly push you over your budget.<\/p>\n It features two air hose ports for use with multiple accessories.<\/p>\n This pump is adjustable, allowing you to customize airflow for your needs and to suit your tank best. It also has a cycle option to limit battery drainage.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tOur Quietest Pick for Small Aquariums\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This air pump is not only super compact, but it includes suction cups to attach to your tank to keep your stand clean and tidy.<\/p>\n It\u2019s extremely quiet during operation and is suitable for tanks in any room of the house.<\/p>\n It\u2019s powerful enough for an air stone in a tank around 5 gallons, but it won\u2019t be able to handle multiple accessories without a gang valve, nor can it run in larger aquariums.<\/p>\n It includes tubing and an air hose, so you can get it set up right out of the box without having to make additional purchases.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\n \t\t<\/p>\n \n\t\t\t\tQuietest Medium to Large Aquarium Air Pump\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t This pump is very quiet when in use, so it\u2019s unlikely to disrupt sleep or conversation in the same room.<\/p>\n Despite its small size and minimal noise, it\u2019s powerful enough to handle tanks up to 100 gallons. However, it only has a single hose port, so you can\u2019t use it with multiple accessories without a gang valve.<\/p>\n It includes air tubing, a diffuser, and a check valve, allowing you to set it up and start using it without making any additional purchases.<\/p>\n This pump is a bit on the pricey side, but it provides excellent value.<\/p>\n Features<\/strong><\/p>\n Pros<\/strong><\/p>\n Cons<\/strong><\/p>\nWhat is an Aquarium Air Pump?<\/h2>\n
