My earliest memories of fishkeeping go back to my pre-school days in the cold weather of the north.

I can remember hunkering down in front of the aquarium, watching the fish for hours because I couldn’t sleep.

I remember all the bettas and guppies, butterfly fish, and angelfish in the freshwater tanks we kept over the years…and I don’t remember a single thing about caring for the fish, even though I know I fed them daily and learned the names of all the equipment that was stuck here and there, jammed in a corner, drooping into the fish tank itself, or hiding behind the shelf on the windowsill nearby.

As an adult, I’m a heck of a lot more aware of all the ins and outs of fishkeeping! These sometimes delicate creatures require a fair bit of high-quality equipment and additives to keep their homes safe, clean, and healthy, and one of the most important pieces of this happy aquarium puzzle is finding the best water pump.

What is an Aquarium Water Pump and What Does it Do?

For those who may be new hobbyists in the aquarist world, a water pump is a critical part of the aquarium in most cases for a number of reasons.

best aquarium water pump

There are a variety of water pump types, each with different components that keep them running and flowing throughout the day and night. And there are hundreds of product options out there to sort through. Specialty pumps that do this or that, in addition to pumping the water. Pumps that use this kind of impeller and pumps that use that kind of spinning shaft, and so on, and so forth.

As the foundation of every water pump, though, there is an impeller.

This is the part of the pump that moves in the water via centrifugal force. Impellers may have a variety of different designs, and honestly most of us can’t tell the difference between them, but they may be straight or curved and can be tucked between either closed solid plates or semi-open with a single plate.

Impellers are attached to shafts that spin, driven by the electric motor. The enclosure around the impeller is what makes the difference, though, as just spinning a shaft in water doesn’t do a whole lot to actually move fluids.

As the impeller spins, the water is pulled into the intake port where kinetic energy is transferred to the water via that spinning of the impeller. This is what creates the water flow of an aquarium water pump.

Why Do I Need an Aquarium Water Pump?

For the health of the miniature eco-system in which your fish live, a water pump is necessary, no matter the size of your tank.

The reason?

They help to aerate the water sufficiently for your fish to have enough oxygen in the water for breathing.

A lot of people may try to sell air stones as an option over a water pump – after all, they make those lovely bubbles! – but they are not enough to produce the levels of oxygen movement through the water that most aquariums need.

While technically your fish and plants may do okay without a water pump, they will do much better with one. Plus a water pump adds a bit to the natural environment feel that your fish and plants naturally seek even if they have never been in the wild.

Types of Water Pumps

There are a variety of water pump types that you could purchase, though the two main ones are in-line and submersible water pumps. Let’s take a look at them so you can determine which is most appropriate for your aquarium setup.

Submersible Water Pumps

The most common water pump type is the submersible pump. They are run completely underwater, usually in the sump of a wet/dry filtration system. They draw the water in from the filter and then push it back into the aquarium or through other devices like aquarium chillersUV sterilizers, et cetera, depending on your exact setup.

Submersible pumps have several advantages over others, which is probably why they’re so popular.

They have quiet operation – more so than many other options – but more importantly, they’re a heck of a lot easier to install because they don’t require you to do any drilling into the bulkhead of your filtration system. They’re also water cooled, since they’re, y’know, in the water, which means they don’t heat up and overload.

If you do decide to go with a submersible water pump, be aware of two things.

First, because they are water cooled, they may push some heat out into the water. These shouldn’t be used in cold water aquariums as readily as other types as they may heat the water too much.

Secondly, they take up space in the sump, so if your space is at a premium in there, be careful of the dimensions of the pump.

In-Line Water Pumps

The second water pump type we’ll look at is the in-line pump. They’re used outside of the water and connected to an inlet hose and outlet hose used to filter your aquarium water.

The big advantage on these pumps is that they’re air-cooled instead of water cooled, which means they add less heat to the water than submersibles. They’re also usually pretty powerful, so they work better for larger aquariums.

In-line water pumps can work in one of two installment configurations, though a rare few work in either. They’ll either work in a pressure setup or a free-flow setup.

Pressure setups normally places the pump before the canister filtration system. The pump forces water under pressure into the canister filter system. This kind of setup receives a substantial amount of back pressure from the filter, which they may or may not do well with.

Free-flow setups usually place the pump after the filtration, like with a wet/dry filter. The pump uses the filtered water from the sump and sends it back into the aquarium or other devices. These setups receive very little back pressure and are more able to move the water with less effort.

Reviews of the Best Aquarium Water Pumps

We’re here to give you the best aquarium pump reviews you’ve ever read. And that’s important, because we were surprised to see how many of the reviews we were reading had really negative reviews from real-life users – and strangely from the review sites we found many of them on.

So it took us quite a while to decide on which ones to review for you.

Ultimately, we reviewed dozens and created the list below from a number of qualities that we look for in the best aquarium pumps that would mean efficient power consumption, low noise levels, and high enough volume to actually pump the water through.

A few of the things we specifically looked for included:

  • Trusted name brands that we’ve worked with in the past and know will produce quality equipment
  • Easy to understand and install devices
  • High enough output for the average aquarium size of 20+ gallons of water
  • Long enough cords that they don’t require extension cords – safety people!
  • Durability
  • Energy consumption efficiency
  • Versatility as much as possible
EcoPlus 396 GPH submersible pump

If you’re looking for an overall, just plain good submersible water pump for your mid-sized aquarium, then you’ve come to the right review. The EcoPlus 396 Submersible Water Pump is a highly durable, long-lasting, efficient, and extremely quiet water pump that’s great for use just about anywhere.

  • GPH: 396
  • Suitable for: Saltwater, freshwater, ponds, hydroponic systems, fountains
  • Noise levels: Extremely low

What We Loved

While this isn’t the most powerful motor on the market – which in many cases is a good thing – we love that oomph this baby puts out. It’s great for aquariums in the 20 to 100-gallon range for high water flow, and larger for the lower flow rates needed for “still” water ponds and aquariums that lake dwelling creatures would need.

Though the pump is submersible, many have reported that it can be used in-line as well, which is pretty great for versatility, depending on your situation. And since it’s also really durable and lasts for years, that makes it great for anyone learning the aquarist skills.

The water pump is extremely quiet, something we absolutely love, and therefore really great for tight spaces – think studios, bedrooms, and offices – as well as larger areas where noise may or may not be as much of an issue.

And, of course, what we love most about this already great quiet aquarium water pump is that it’s a really durable, long-lasting option. While we haven’t been reviewing it long enough to say this, we’ve seen so many reports from real-life users who say it’s lasted them for years and years.

We love that it’s a reasonably priced option that doesn’t have to get replaced all the time.

What We Didn’t Love

The only real issues we’ve potentially see with this water pump is that it’s not really that great for some when being used in-line.

While it can be used this way, there were some issues for several commenters that demonstrate that you might want to just use as a submersible instead.

Our Verdict on the EcoPlus 396 Submersible Water Pump

All-in-all, we just have to say this is the quietest submersible aquarium pump that works efficiently and lasts forever. You won’t have to keep rebuying over and over again. You can install and maintain, and know you’re keeping your aquarium fresh, clean, and healthy with this pump assisting the other systems in there.

#2. Hydrofarm Active Aqua 1000 GPH

Hydrofarm Active Aqua Submersible Water Pump

For anyone with a large aquarium, you’ll want to consider the Hydrofarm Active Aqua Submersible Pump 1000 GPH option. It’s got an output of 1000 gallons per hour and it’s specially designed for large gallon reservoirs of water.

It’s also designed to last and work both indoors and outdoors – so, yes, it’s even great for your ponds.

  • GPH: 1000 (although it’s also available in other sizes down to 40 gph)
  • Suitable for: Indoor, outdoor 100+ gallon tanks
  • Noise levels: Reasonably quiet

What We Loved

First off, we love that this pump was designed with large aquariums and other bodies of water in mind. It moves 1000 gallons an hour, meaning no need for additional pumps to cycle through the water each day. And despite the size, it’s a fairly energy efficient aquarium pump.

We also love that this comes from an environmentally conscious company. They make the pumps without oil and in an environmentally safe way.

The fact that it’s made for both indoor and outdoor use also says a lot about this commercial grade water pump. It can handle anything you throw at it and keep going. It’s incredibly durable and lasts for years. Its electrical magnetic air compressor system is housed in a high-quality aluminum case and the pump itself has a wear and tear resistant cylinder and piston to keep it going for ages.

The pump can power multiple air stones at once with high water output, all while being fairly quiet.

Finally, these submersible aquarium pumps are energy saving, so you won’t spend a bundle on the electric bill to keep it running.

What We Didn’t Love

The only potential issue we’ve seen with this Hydrofarm utility pump is that some of them can get warm after an extended period of time running.It seems like it would be a good idea to give the pump a rest every so often to prevent the overheating issue. You may also want to invest in an aquarium chiller or two is this winds up being a problem. 

Our Verdict on the Hydrofarm Active Aqua Submersible Pump

The Hydrofarm Active Aqua Submersible Pump is a fantastic option for anyone running a large aquarium setup – or pond – and needs intense water movement. The pump can work through 1000 gallons an hour, has an incredible record for durability, and comes from a manufacturer that really knows its stuff. Just give the pump a break every now and then to prevent overheating.

#3. Homasy 80 GPH

Homasy 80 GPH Submersible Water Pump

For those looking for a basic, easy to use, easy to maintain aquarium water pump, then you’re looking in the right place. While the Homasy brand isn’t as well-known in fishkeeping as, say Tetra or Aqueon, they have been proving themselves manufacturers of reliable, high-quality goods for a while now.

And the Homasy 80 GPH submersible Ultra-Quiet pump is definitely one of our top-contenders for best fish tank water pump.

  • GPH: 80 gallons
  • Suitable for: Small size freshwater aquariums, small fountains
  • Noise levels: Reasonably quiet

What We Loved

The first thing we’ve noted in our experience and research is that this is a reliable and durable water pump that can handle a reasonably strenuous life. It’s designed for small aquariums and fountains – even tiny ponds – and can even elevate a column of water 2.6-feet in height.

We love the adjustable flow rate of the pump. There’s an adjustable knob that lets you change up how much or how little a flow you want. This makes it especially great for still water situations like goldfish tanks where low water flow is necessary for healthy, happy fish.

The pump is super easy to clean and maintain, which is another huge bonus for us. You can easily detach and separate pieces for the semi-annual cleanings and reattach without issue, even if you’re not the handiest person on the planet.

We also love how small the water pump is. It’s powerful enough to do the trick, but only 1.87-inches by 1.68-inches by 1.24-inches. That means it’s easy to hide or disguise in your small aquarium, and no one will be the wiser.

Finally, we love how truly adjustable and multi-functional the pump is. It has two different nozzles that you can vary for the water flow rates for the perfect setting for your setup. The maximum flow rate and the low flow rate are equally beneficial, depending on your fish tank type.

What We Didn’t Love

While we haven’t seen any specific issues with this, we have found in our research that some folks have found the pump to be a bit noisy. It’s possible they’ve used them improperly, had a faulty pump, or otherwise experienced fluke – since the tech behind the volume control is pretty solid.

Generally speaking, though most people agree that it’s an uber-quiet aquarium water pump and can be used in tight spaces where you have small fish tanks a lot of times.

Our Verdict on the Homasy Submersible Ultra Quiet Water Pump

Ultimately, if you’ve got a small aquarium, small pond, or small water fountain, this is the water pump you should look into. It’s reliable, durable, easy to use, clean, and maintain, and it actually does the trick, all while being small enough few people would ever notice it – even you.

Current USA 6010 1900 GPH eFlux DC Flow Pump

The Current USA eFlux DC Flow Pump comes from another well-trusted brand in the fishkeeping industry.

It’s the best pump to use for saltwater aquariums and the best inline aquarium pump or best external aquarium pump.

It’s great for ponds moderately sized aquariums, has decent flow rates, adjustable knobs for the flow rate, and is easy to use, clean, and maintain.

There are three size options, though all of them are pretty huge (1000+ GPH).

All-in-all, it’s a very good choice for your saltwater aquarium.

How to Choose the Best Aquarium Water Pump

As you can probably assume from the setup information for the three types of pumps we’ve talked about, there are several things that matter for choosing your aquarium’s circulation pump.

Filtration System

Because the type of filtration you use affects the type of pump you can use, make sure you know what you’ve got working for you.

Do you have a sump that can fit the pump you’re looking at, or should you go with a submersible pump instead?

While usually size doesn’t matter, in this case it actually does. The wrong pump will be too large for your setup and therefore useless to you.

Desired Flow Rate

Secondly, the desired flow rate for your aquarium water is vital in your water pump selection.

What species do you stock? What kind of flow rate do they do best with?

Be sure to study up to verify if they prefer high flow or low flow. This is based upon their natural environment.

For example, planted aquariums that house fish like goldfish need a low flow rate, while reef tanks will use a higher flow rate since, well, the ocean naturally has a much higher rate than a stagnant pond.

Additional Devices You Use

Next, you’ve got to consider which devices you use.

Are you sending the water through a UV sterilizer, a water chiller, protein skimmer, or other device? Or are you keeping a pretty basic aquarium?

The setup can determine which options work with your new pump.

Plumbing and Head Height

Finally, what type of plumbing are you using for your system? Are there elbows, sharp turns, et cetera, or basically straight lines? Where is the plumbing positioned? Beneath the tank, alongside the tank, behind the fish tank?

Consider the total distance the pump will be required to pump the water.
