Aquarium Maintenance Recommendations – Pumps for Aquariums

An aquarium is an enclosed space. To enhance quality of life for its inhabitants, look at pumps for aquariums.

Pumps circulate or direct water to the filtration unit for cleaning. As a bonus, water movement is created, which is perfect for certain fish and corals that depend on currents.

Some pumps siphon water through hoses, which is handy during maintenance and when replacing existing tank water with new tank water.

There are pumps that work when submerged and others that work outside the tank. Internal pumps tend to add heat to an aquarium, so check the water temperature as other aquarium parts such as heaters may require adjustment. External pumps don’t create heat, but because they are out of water, they may produce noise.

There are pumps that offer several functions in one and that can be used both internally and externally.

Something else to keep in mind is the pump’s flow rate or gallons per hour. Saltwater aquariums need a higher flow rate as saltwater is denser. If the tank contains saltwater coral or fish, make sure that the aquarium pump is rated for marine use.

When in doubt, check online forums or a pet supplier for assistance.

Pumps for aquariums are a helpful add-on to a tank environment. There are two main types of aquarium pumps: air pumps and water pumps. Air pumps work simply through pressurized air, producing bubbles in the tank. Water pumps use water pressure. Let’s take a look at water pumps.
 
Internal or submerged pumps tend to be quieter. But because they run in water, their motors can heat the water. Check the tank temperature before and after installing an internal pump. The aquarium likely runs a separate heater, so make any necessary changes to the heater’s setting.
 
Some external pumps, also known as in-line pumps, can be adapted to siphon water in and out of the tank, which is excellent for maintenance. But, they can be noisy. As the primary purpose of a pump is to circulate and direct water to the filter so that the water can be cleaned, knowing that these two different apparatuses work in harmony is necessary. The type of filter determines the type of in-line pump.
 
Flow Rate or GPH (Gallons Per Hour) is another consideration. Experts recommend that the overall volume of water in the tank be turned over at least several times an hour. To calculate the flow rate of a tank, multiply the number of gallons of the tank by five. A 40-gallon tank will need a minimum of 200 gph flow rate. If the aquarium carries saltwater fish or corals, the flow rate must be higher, due to saltwater being denser than fresh water.
 
Note that saltwater is corrosive, so the aquarium pump must be rated for marine use.
 
Multi-Function Pumps can also create water movement, which is necessary for growing corals and for emulating currents for fish accustomed to fast flowing streams. The multi-function pumps can offer the bonus of aerating the water and adding oxygen.
 
Remember: this is an enclosed space and water can become stagnant. By introducing motion to the water, pumps can ease maintenance AND enhance the life of the aquarium’s inhabitants. When in doubt, check online forums or a pet supplier for assistance when it comes to pumps for aquariums.
