How to Choose an Aquarium Sump Pump?
Before we get into how to choose the right sump pump, it’s important to first understand what a sump is for so that you can figure out whether or not you really need one and what kind of setup would benefit your tank.
What is a sump for?
There are a few different uses for an aquarium sump. They’re usually located underneath or next to the main aquarium because the water gets cycled from the aquarium to the sump and back again.
A sump can be used as a separate area to keep all the equipment your tank needs to function so that you don’t have to take up any precious space inside the tank or deal with anything unsightly hanging off the tank.
A sump can also be used to set up a filtration system and is an effective way of increasing the water volume to have a more stable setup which is especially useful when you’re working with something more delicate like a reef tank.
What things should I look for when choosing a sump pump?
Choosing a sump pump is not as difficult as it might sound. Here are some of the things to keep in mind:
1. Submerged or dry? Some sump pumps have to be submerged to work properly while others can run wet or dry. This is completely based on personal preference but you should have an idea of what your set up will be before you decide.
2. Rate. How many gallons per hour of flow do you need? A lot of these pumps are adjustable and give you a little wiggle room but making sure the pump is powerful enough to support your setup is essential.
3. Prefilter. Prefilters are very important because they protect the inside of the pump from debris getting in. Some of these pumps have one included. If not, you’ll have to supply one of your own.
4. Running temperature. Because your sump pump comes into contact with the same water that circulates through your aquarium, it’s important that it runs cool so that it doesn’t affect the water temperature.
5. Sound. Generally, it’s preferable to have a pump that runs quietly so it doesn’t disturb you or the fish and other creatures you have living in your aquarium. A lot of these pumps are pretty quiet but that’s not always the case.
Conclusion
Getting the right sump set up can make your aquarium easier to maintain and keep the water perfectly balanced so your fish and coral thrive. The most important part of any sump system is the pump.
