About Sumps and Sump Pumps
A sump system is a secondary water reserve for an aquarium. It holds extra water and houses a lot of aquarium accessories that would otherwise clutter up the main tank. The sump pump is the most important part of a sump setup because it is the main connection between the sump and your main aquarium. It moves the water through the sump and back again; it needs to be powerful enough to complete that cycle regularly.
It goes without saying that the best sump pumps can make a huge difference in the regular maintenance of your aquarium. Sumps are most common in marine and reef tanks because it can take a lot of equipment to regulate a tropical environment, but they can also be beneficial for a freshwater aquarium that has grown to a large size. If you are looking to get started with your sump system, you will first need to find a reliable sump pump to keep it running smoothly. We have reviewed up some of the best sump pumps on the market, but first let’s find out what you should be looking for in a sump pump.
Buyer’s Guide: What to Look for in a Sump Pump
There are a huge variety of sump pumps out there, and there are a lot of factors to consider when deciding which one is the best fit for you. You will need to keep in mind the size of your tank, the space available for your sump system, and the type of environment you are creating for your fish. It is also important to remember your personal preferences- a pump that might be great for one person might not be right for another. It depends on what kind of maintenance you feel comfortable with, how much control you want to have over the system, and what your plans are for changing or expanding your system in the future. Some of the pumps available include a lot of the extra equipment and features that you would otherwise have to source yourself, but do not provide a great deal of flexibility. Other options offer the bare bones in terms of setup, but with a quality pump that you can further customize to meet your specific needs. Take your time considering what features are most important to you before you start your search.
- Rate of water flow: Sump pumps all have varying rates of water flow, which is the rate at which the water is being pulled through the pump. If you have a very large tank, you will want to make sure that the sump pump you choose has a high enough water flow rate to support your tank. There are fixed and adjustable flow pumps available to choose from, depending on whether you want a constant flow rate or something that can be tweaked as your aquarium expands. Water flow is measured in gallons per hour, often abbreviated as GPH.
- Inline or submerged sump pump: The most basic question you will likely be asking yourself as you start looking for a sump pump is whether you want a submerged or inline pump. A submerged pump is designed to be run in the water, and an inline pump is installed on the outside of the sump. This is a matter of personal preference and space- consider the size of your sump, the sump pump, and how much room around the tank you have for other equipment. It is also important to remember that an inline pump will require some extra plumbing to allow the water to pass in and out of the pump from the outside. Many people are able to do this themselves, but if you are after easy installation options, a submerged pump might be best for you.
- Removable filters and maintenance: Another thing to consider is whether or not the pump has a screen or pre-filter. These will prevent debris from getting in the main mechanism of the pump and gumming up the works. Many sump pumps come with a filter for this purpose, and others don’t. Sump pumps without a filter will need to have one supplied externally- so again, it is a question of how much control you want over your system and how much space you have to dedicate to extra supplies. It is also important to consider how often you would like to have to clean out your pump. An external filter might seem cumbersome in the short term, but easier to maintain long term if you prefer to clean less often.
- Running Temperature: Running temperature is another factor to consider. Like many pieces of machinery, a sump pump heats up once it gets going. Your pump is constantly drawing water in and pushing it out again in a cycle, which will eventually lead to an increase in water temperature if your pump is running hot. This will be something to monitor in order to keep the water temperatures in your aquarium stable, especially for tropical aquariums, where your fish and plants are more likely to be affected by fluctuating temperatures. If your sump pump has a higher running temperature, it might lead you to invest in a chiller to keep things regulated. It is also worth noting that submerged sump pumps come into closer contact with the water and are more likely to heat things up than an inline pump.
- Noise level and energy use: The more accessories that you add to your tank, the more likely it is that the volume level will go up. If your aquarium is set up in a place where added noise will cause a disturbance, you might want to prioritize a quiet sump pump model. It is often the case that submerged sump pumps run more quietly than inline pumps.
You will also want to check the energy rating of your sump pump and make sure it is something you are able to keep running without your energy bill skyrocketing. Most sump pumps run on a standard household voltage, but the wattage varies from pump to pump. Investing in an energy efficient sump pump up front might save you more money in the long run.

There are many other sump pumps on the market that might be just as well suited as these to your sump system, so feel free to keep searching until you find the best sump pump for your needs and budget. If your aquarium is on the smaller side, your might even be wondering if a sump system is appropriate for you, or if you could get by with a typical filtration system. While there are no rules as to who can and cannot set up a sump system for their aquarium, there are certain instances where sumps are recommended.
When is it recommended to have a sump system?
Sumps are most often recommended for marine tanks, which require a lot of extra equipment. Saltwater tanks often need a heater, a chiller, skimmer, calcium reactor, several filter media and more. These items would quickly overwhelm a display tank, so it makes sense to hide them away in the sump. Additionally, water changes are more risky and complicated for larger tanks, where the ecosystem is balanced for the fish and plants alike. A sump makes it easier for water changes to properly mix with the existing water to prevent any sort of shock or imbalance. The sump pump is very important in the sump system because it is responsible for the exchange of water between the sump and the display tank- without it, the sump would be useless.
How does a sump system work?
When searching for a sump pump, it helps to have a solid understanding of how the sump system works. To begin, water from the display tank (your aquarium) enters an overflow chamber as the waters rise. The water in this chamber drains into the sump. Once the water is in the sump, it runs through the equipment that is kept there (heater, chiller, filter, or anything else you might have set up), before reaching the sump pump. The sump pump pushes the water back up into the display tank. The goal is to have the sump pump running at about the same speed as the water draining from the overflow chamber, to create a constant loop of changing water.
What can I do to keep my sump pump clean?
Sump pump maintenance often varies depending on how hard the pump has to work to move the water and how large your aquarium is. However, there are a few maintenance tasks that you can perform to keep it running smoothly for a long time. Check on your sump pump once a month to see if it requires any cleaning- even if your water flow has not changed. A routine cleaning can help prevent buildup that can lead to a more challenging blockage. To clean the pump, rinse any debris out of the filter and wipe down the impeller.
A sump system is a great way to maintain a large aquarium. The increased water volume makes it easier to keep your ecosystem balanced and is great for keeping excess equipment out of the display tank. It can also make it easier to do water changes and keep everything in great shape without disturbing your fish and plants. Sump pumps are the most important part of any sump system, because it is responsible for keeping the water flowing through the cycle. A great sump pump is the key to success with your sump system, and choosing the wrong one will definitely lead to some headaches. Now that we have covered what to look for in a sump pump and some of the great options on the market, you can feel confident with your next sump pump purchase.
