Submersible aquarium water pumps draw in water through a filter to produce clean water that is sent back into the aquarium. Basically, they are a must-have for aquariums as they are essential to the health of your aquatic pets and their environment. The abundant water movement, ample oxygen, and clear water that comes from a submerged water pump will keep your school of fish happily swimming. Whether your aquarium is big or small, fresh or saltwater, spacious or crowded, a water pump is essential. Here are some fantastic submersible water pumps that we recommend.
What to Keep in Mind When Shopping for a Pump
If you are looking to maintain your tank’s healthy environment with a water pump, consider these key factors:
- Water Type: Different environments require different flow rates. If you have a saltwater aquarium, you will need to look for a pump with a more powerful flow. Some pumps are even built to create ocean-like waves the help to mimic your fish’s natural habitat. Freshwater aquariums should avoid pumps that create currents, as traditional freshwater pets need calmer environments to thrive.
- Pump Size: If you have a small tank, lots of aquarium decor, or multiple fish, there are some tiny pumps on the market that will fit your fish’s lifestyle. Keep an eye on the power of a mini pump, as only some can still create the necessary high flow rates. Also, think about how you’re using the pump. Do you want to be able to hide the pump to ensure a beautiful display?
- Functions: There are so many design variations and functions in water pumps that purchasing one can feel overwhelming. You will find submersible aquarium pumps that light up in an array of colors for a beautiful shimmer that will mesmerize guests. There are also pumps that sit quietly behind rock or coral and won’t disturb the fish. If your pet has highly specific needs, consider a water pump that has time-interval, wave, and power controls.
