Air Pumps for Aquarium Use - What Are They for and Why Are They Necessary? (The First Tank Guide) Support and Share the First Tank Guide: OK, this one's relatively simple. An air pump is a device used to move air, possibly under pressure. Typical aquarium air pumps move air by using an electromagnet to rapidly vibrate a rubberUnfortunately, this has the side effect of creating noise as well as moving air. Why would you want an air pump for your aquarium? Well, there are many uses of an air That depends on what you mean. If you have a filter that is run by an air pump, then the air pump is necessary, as without it the filter will not operate and you are not going to be gaining benefit from having that filter on If you have an action ornament that is run by an air pump, and you wish to have it operating as designed, then, again, the air pump is If you wish to have an air stone giving off a cascade of bubbles as a decoration in your tank, than, again, the

air pump to run this air stone is arguably necessary. One of the most common misconceptions in the aquarium hobby, possibly second only to "fish will not outgrow their aquarium", is that you need an air pump and air stones to provide sufficient oxygenation to that tank to keep the fish healthy, and that the air pump provides oxygen to the water. In fact, the air pump is not necessary to keeping fish, except as noted above. fish tank siphon youtubeAn air pump will notfish tank vacuum hose directly put oxygen into the water, what it will do is two things:fish tank siphon youtube Gas exchange - where the water dissolves oxygen and other gasesaquarium air pump canadian tire

from the air and releases excess carbon dioxide and other gases to the air - occurs over any and all surface area where the water hasBy increasing the surface area of the water, each bubble gives the water further opportunity to release carbon dioxide and take up oxygen. However, this improvement from an air pump is shadowed by the improvement in circulation that the air pump canThe improved circulation will move highly oxygenated wateraqua one aquarium digital internal thermometer from the surface lower in the tank allowing water with more carbonmakan di lembang bandung dioxide and less oxygen to the surface of the tank where id can release its carbon dioxide and take up oxygen. Of course, if you already have a good filter that is providing sufficient water circulation, then the benefit you will

receive from an air pump is minimal. There is no hard and fast rule for choosing an air pump. pumps are rated for different sizes of tanks, but these ratings are, actually, nearly irrelevant to choosing the correct air pump. If you are using the air pump only to operate an under gravel filter, and your tank is a standard size, then the tank size ratings on an air pump are probablyHowever, if you are doing anything else with the air pump, or if your tank is not a standard size, then the tank size ratings for an air pump are highly irrelevant. Here are some guidelines to have in mind when you are choosing an air pump for your aquarium: When choosing an air pump, pick one a little larger than you initially think you will need. This larger air pump will help you by compensating for underestimating when choosing the air pump or by providing a little room for expansion if you decide you want that Site Map and FAQ Top of This Page

Moving water creates aeration by constantly mixing the surface with the rest of the water. Pumps move much more water than airstones can, and thus they provide greater aeration, despite the fact that no bubbles may be produced.

Many species of fish will not thrive without proper current in the tank. In addition, currents prevent detritus from accumulating. When devices are located outside the aquarium, one or more pumps are needed to move the water through a circuit that goes from the tank to the peripherals and back. Gravity can be used for part of the circuit, but at least one pump is needed. In power filters the integral water pump usually pumps water from the tank into the filter, from which it returns by gravity, while in canisters the water normally drains by gravity into the canister, from which it is pumped back to the tank. Many marine invertebrates rely on the pulsing currents of breaking waves to keep them free from settled debris and to bring them food. Riverine animals are adapted to a strong current that flows in one direction, but reef animals are adapted to alternating currents. Revolving pumps oscillate much like a fan, varying the flow direction constantly. Timers utilize two or more pumps, turning them on and off in sequence, to deliver pulses of current from different directions.

Surge devices pump water to a vessel above the aquarium, which periodically releases the accumulated water in one powerful dump, effectively mimicking wave action. The first factor in determining what pump you need is the volume of water you need moved. If you are running a filter or skimmer, it will be rated for a certain volume of water per hour. Generally a turnover of about 6 gallons per hour is recommended for most filtration; thus, if you have a 40-gallon tank, use a pump that moves about 240 gallons per hour. Remember to take the head into account. This is the height the water has to be pumped against gravity. While minimal for hang-on filters, it can be considerable for a canister system—often several feet from the floor to the top rim of the aquarium. Output volume drops off extremely quickly as head increases, and only the most powerful units can handle more than a few feet at reasonable flow rates. Because it is much more corrosive, salt water requires that all pump parts in contact with water be highly corrosion-resistant.

A pump rated for salt water can be used for fresh, but the reverse is not true. There are two reasons people use air pumps. The first is that they are using an air-driven filter. Inside box filters and sponge filters use air to move water through the filter. The second is that people like bubbles. In fact, for some aquarists, a tank isn’t right unless there is at least one stream of bubbles rising in it. A side effect of both of these uses is that the current created by bubbles rising in an aquarium contributes to the aeration of the water. You certainly don’t need an air pump, since despite the name “aeration,” air bubbles are not necessary or even basic to gas exchange, but you certainly can use air for aeration. Electric air pumps create a stream of air under pressure. Pressure is not the same as volume. The volume of air pumped out determines how many air-driven devices can be run by the pump provided pressure concerns are kept equal. The resistance posed by an air-driven device determines the pressure needed to run it.

Airstones create more resistance than an open tube, so on a given pump you can run more undergravel filters that simply have air tubing run to each riser tube than those that use an airstone in each riser. Also, the deeper the water, the greater the resistance. A pump capable of running several devices in a 12-inch-deep aquarium might not be able to run even one in a 24-inch-deep tank. A few simple precautions will get you maximum performance from your pump. If your pump has more than one outlet, use a valve or a tee to combine their output. This assures that the backpressure on each diaphragm is equal, which prevents uneven wear and early failure. Place a check valve between the pump and the aquarium. It permits air to flow into the outlets in the aquarium, but it prevents water from siphoning back from the tank into the pump in the event of a power failure or in case the airline gets disconnected from the pump.
