A pump designed for an aquarium is a very important device. Its task is to form the flow and saturate the water with oxygen.
Sometimes aquarists with its help fill the aquarium with water. If such a device works together with a pump with a special foam sponge, it will be able to function as an internal filter for mechanical cleaning of the reservoir.
His main task is to ensure the normal functioning of the aquarium: the swinging and mixing of water, the supply of oxygen. It is he who creates the pressure necessary for the operation of the external filter.
If necessary, helps the formation of flow in water, contributes to the work of the aerator, slows down the process of contamination of the tank.
There are several variations of this device:
- internal type;
- external (or external);
- universal model.
In these reservoirs, oxygen enters through the flow of wind and water oscillations. In a closed tank, aquarium pumps are responsible for this process.
- By design. There are piston and membrane options.
- By installation. There are submersible and external.
Piston devices will last a long time, and they are more powerful than membrane ones. Their disadvantage is that they make a lot of noise and vibrate.
Such devices should be used for aquariums, which in volume more than 200 liters. Diaphragm pumps operate silently and consume minimal amounts of energy.
They have one drawback – they are suitable for containers up to 150 liters.
Equipment that is submerged under water is attached using clamps or suction cups. The external model is installed behind the aquarium.
It is designed for small tanks and is also suitable for raising demanding fish. Aquarium pump can be easily fixed with your own hands.
When choosing a pump, you should consider the power of the device and the volume of the aquarium – you can see a good selection of pumps for the aquarium here. For service of small enough low-power model.
Especially if it will be used only for water supply. For a capacity of more than 250 liters will need a more powerful option.
It is also necessary to take into account the height of the rise of water (this figure depends on the volume of the tank). The larger the capacity, the more powerful the pump is.
Effective is the one that pumps from 3 to 5 volumes per hour.
Another important point when buying a pump is the type of aquarium (saltwater or freshwater). For each variety, you need to choose the appropriate model.
Instruction The simplest pump consists of a glass in which there is a sponge filter, a motor and water pipes. Let’s figure out how to install the device in the aquarium: Acquired pump should be assembled according to the instructions. Many modern models have two types of fasteners: vertical and horizontal (suction cups); when mounted on suction cups, vertical fasteners should be removed.
Next, choose a suitable place on the wall of the aquarium, preferably in the corner, press the suction cups against the glass. If mounted on a vertical bracket, attach it to the edge of the tank. To improve cleaning and aeration, it is better to direct the water flow along the wall of the aquarium.
If there is a need for two devices, their flows should be directed in different directions. It is necessary to install the pump when all the decorative objects and the ground are already placed in the tank. Important!
The submersible version of the device should not be located above the water and work “dry”. Also, do not check the operation of the internal filter in an empty aquarium.
During operation, the external filters do not cause any trouble to their owners. Aquarist should only remember that disconnecting equipment at night is strictly prohibited.
If for any reason the electricity in the house was turned off for 12 hours or more, then the nitrifying bacteria on the substrate will die, and the aquarium will need to be restarted. Such equipment should work around the clock, which will ensure high-quality purification of aquarium water.
Care of the external filter is not difficult. Once a month, the housing should be opened and the sponges cleaned from existing contaminants.
This work is done as quickly as possible and takes 5−10 minutes.
After flushing the jaws, you also need to pump the system from the air, for which purpose a hand pump is used, which expels the unwanted air out of the tubes.
Approximately once a year, a major flushing of the system is performed. For this kind of work, 10–15 liters of water should be drained from a tank in a small volume. The filter is disconnected from the power supply, disassembled, all fillers are washed in a basin of water, after which the cleaning equipment is assembled in reverse order.
Such work usually is not difficult and takes about 20-30 minutes.
Installing an internal or external aquarium filter is quite simple. It is only necessary to determine the location, observe the accuracy of performing the assembly, turn on the device in the network only after the complete installation of the equipment.
In the future it will be necessary to properly maintain the equipment., regularly flushing it, and not allowing a long power outage, which subsequently leads to the need to re-run the filter and the entire aquarium.
The main advantages of a homemade device: saving money; if you know how to work with your hands, assembling a pump from improvised means will not take much time; the device can be modified according to your desires and needs of the inhabitants of the aquarium; the device can be given an aesthetic appearance that is appropriate for the decor of the container. A minus can be considered possible errors in the work, for example, insufficiently strong sealant or inaccuracy in the calculations.
Features of the selection and use of pumps for marine aquarium
Marine aquariums usually contain corals and various types of sponge as natural water purifiers. And those and others, as well as fish in their natural habitat are dependent on the flow.
All life cycles, feed availability, seasons change for marine inhabitants are associated with the current. Considering this important factor, the pumps with currents that also perform the function of cleaning and aeration are installed on the tanks with the inhabitants of the sea waters. You need to take into account such nuances: For ten to twelve hours, the pump must be turned off, simulating calm.
The volume of pumped water per hour should be about fifteen times the volume of the tank. The flow of water is directed to the bottom stones.
For large containers it is recommended to purchase two devices.
Independently assemble the device for their silent pets is not difficult and not long, especially for those who are at least a little oriented in the operation of such devices. In the absence of skills, you can search for a budget option, but in any case, this device is vital for aquatic inhabitants.
All pumps for aquarium differ in power and performance. There are universal devices that are suitable for fresh and salt water.
They can be both under water and outside the tank.
- Eheim. Suitable for complete immersion in water. Power can be easily changed with a special regulator. It is possible to make an artificial waterfall, as well as increase circulation.
- A lift pump for a home aquarium is used for seawater and fresh water. If desired, you can set a timer to stop working for 10 minutes. Equipped with a controller that allows you to change the flow force and power.
- The model is manufactured in Poland, and it is equipped with an energy-saving engine, it has a flow regulator, therefore it can be used as a circulation pump.
- The submersible device, which is characterized by small dimensions. It is used to create the movement of water, and also saturates it with oxygen.
- Resun. This model is often acquired by people who keep small aquariums at home. It is inexpensive, because it has a small capacity – about 200 l / h.
- Tunze. It consumes the minimum amount of energy, works silently and is compact. Some models are equipped with special protective grills.
The pump in the aquarium should be silent, especially if it is located in the bedroom. When choosing a model, you need to focus on its characteristics, so as not to be mistaken with the purchase.
