Pond pumps will help to aerate the water in your pond, keeping fish healthy, and preventing the stagnation that can lead to a build-up of green algae.

Pumps come in all sizes and strengths, and can be submersible or external, meaning they either sit below the water line, or are installed outside your pond. The best pump for you will depend on a variety of factors, including the size and location of your pond.

To help you decide which pump is right for you, we’ve selected 5 of the best pond pumps on the market, based on their flow rate, energy consumption, filtration systems, and effectiveness at clearing and aerating your pond.

With one of these pumps installed, your water will be algae-free in no time!

Best Pick: Blagdon Inpond 5 In 1

Our best pond pump comes with 3 fountain heads, a water filter and a UV clarifier, to clear your pond of algae in no time

This 5-In-1 Inpond Pump by Blagdon tops our list because not only is it an exceptional pond pump, but it also has a built-in UV clarifier, automatic night-time LED spotlight, and 3 fountain options – this is a complete pond management solution.

The pump offers a choice of mechanical or biological water filtration, and the filter system includes a polymer wool pad cartridge to remove cloudy particles, and ceramic bio-media, which supports friendly bacteria. Combined with the UV clarifier, these features will clear even the greenest pond of algae. 

Choose between daisy jet, super daisy jet and bell jet fountain heads, to customise the appearance of your fountain. The pond pump is super simple to install, with the integrated handle making it easy to lift the pump in and out of the pond. The filter cover can also be lifted off to access the internal media and foam, making it easy to maintain. 

It has a maximum flow rate of 700L/hours, and is suitable for ponds up to 3,000L – which actually isn’t a lot, so if you’ve got a medium to large sized pond, you’ll need to look elsewhere. For small ponds though, this high-quality submersible pump is packed full of features, and will keep your pond aerated, well-lit, and crystal clear.

Pros

  • Complete in-pond solution.
  • Includes a water filter, low voltage pump, flow adjuster, LED spotlight and UV clarifier.
  • Also comes with 3 fountain options.
  • Will clear your pond of algae quickly, and keep water clear.
  • Easy to install, transport and maintain.
  • Comes with a 3-year manufacturer guarantee.

Cons

  • Not the most affordable option.
  • Only suitable for small ponds, up to 3,000L.

Value Pick: All Pond Solutions Pond & Aquarium Water Pump

This simple, no-frills pond pump works well and is highly affordable, which is why it’s our value pick

If you’re looking for the best value option, you’ll find this Pond & Aquarium Water Pump from All Pond Solutions hard to beat on price.

There’s no filter, UV clarifier or fountain on this one – it’s a simple, submersible pond pump, designed to aerate your pond. It’s made from a combination of ABS plastic and corrosion-resistant ceramic, and many users report that it lasts upwards of a year, before needing to be replaced.

The pump has a maximum flow rate of 1,400L/hour, which, whilst not huge, is still double that of our top pick. This makes it suitable for use in small to medium-sized ponds, although it could be too much for very small water features.

The fact that it’s submersible, and there’s no fountain, means it’s not too noisy once it’s installed, which might appeal to users who want to forget the pump is even there.

Overall, if you’re looking for a simple pond pump to aerate your water, this one does the job, and at a fraction of the cost of many on the market – just don’t expect it to last as long. 

Pros

  • Made from durable ABS particles and corrosion-resistant ceramic.
  • Highly affordable – our lowest priced pond pump, by far.
  • Submersible pump means there’s no audible sound.
  • No fountain head means there’s less to clean and maintain.
  • Maximum pump flow rate of 1,400L/hour is suitable for small to medium-sized ponds.
  • Includes 15mm outlet adapter.

Cons

  • Basic pump design – no filter or UV clarifier.
  • No other additional features, such as fountains.
  • Unlikely to last as long as more expensive models.

All Pond Solutions UV Steriliser Filter Pump

This UV sterilising pump will keep your pond clear, whilst also providing a choice of fountains

If it’s important to you that your pump has a UV steriliser (which will help to keep down the algae), then All Pond Solutions also offer this UV Steriliser Filter Pump, which might be the better option.

This one is similar to our top pick, in that it comes with not only a UV steriliser but also 3 fountain heads, for a variety of fountain styles. A splitter is also included to allow you to divert water to a waterfall and the flow rate is adjustable for both, giving you full control over your water features.

With a maximum flow rate of 2,500L/hour, this is our most powerful pump yet and should be plenty for a small to medium-sized pond of up to 4,000L in volume. Bear in mind that a minimum depth of 52.5cm is required for fountain use.

The pump consists of a single smart unit, with a single power cable, and is very easy to install. A coarse foam filter and 3 filter media baskets serve to remove particles from the water, and ensure that your pond remains clear and non-cloudy.

In case of any problems, a 24-month warranty from the manufacturer is here to put your mind at ease. Overall, this is a reasonably-priced option, considering the construction, and will clear your murky green pond water in no time.

Pros

  • Includes 11W UV steriliser with on/off indicator.
  • Comes with 3 fountain heads, and a splitter to allow you to divert water to a waterfall.
  • Maximum flow rate of 2,500L/hour makes it ideal for small to medium-sized ponds up to 4,000L.
  • Easy to install.
  • 24-month manufacturer’s warranty.

Cons

  • Can be difficult to tell whether the UV light is working.
  • Not safe for all wildlife, as it will suck in all particles up to 6-8mm.

Jebao XTP-10000 Compact

This simple pond pump has a low power consumption, making it more economical, and eco-friendly

For an even more powerful option, this Jebao XTP-10000 Eco Pond Pump is capable of reaching a flow rate of 10,000L/hour, and is a great choice for larger ponds.

Despite the high flow rate, it has a low energy consumption of just 68W, and is said to save up to 65% energy, compared to similar designs. This is the pump to choose if you’re concerned about the environment, and/or your power consumption.

The cage is designed to prevent blockages, but it’s still reassuring to know that an electronic detection system will power-off the pump in the event of a blockage or overheating, to prevent damage to the motor.

However, this pump is inferior to some of the others we’ve featured in that it is just a pump, designed to push water through a filter, or into a waterfall. There’s no built-in filter or UV clarifier to tackle algae and cloudiness within the unit, and so, even though this is one of our most affordable options, it could work out more expensive if you don’t already have a filter.

Ultimately, if you just want a pump, this one is a solid option, and it’s economical – but if you want a filtration system or UV clarifier built-in to your pond pump, you’ll need to look elsewhere.

Pros

  • High maximum flow rate of 10,000L/hour.
  • Low energy consumption means it’s more economical and environmentally-friendly.
  • Automatic power-off function in the event of overheating or a blockage.
  • Easy to clean and maintain.

Cons

  • Simple design – no built-in filter, UV clarifier or fountains.
  • Case can come unclipped when knocked.

All Pond Solutions Pressurised Filter

This is our most expensive pond pump – but that’s understandable, considering the number of features on offer

Our final pond pump is also our third model from All Pond Solutions. Their Pressurised Pond Filter is the most expensive pump on our list, but also one of the most advanced.

Included with this one is a pump, filter, heavy duty flexible hose, and jubilee clips. A built-in UV light helps to prevent the growth of algae, and eliminate harmful parasites and microorganisms that may be dangerous to fish. 

There’s both a biological and mechanical filter, with 2 x coarse and 2 x fine foams supplied, for efficient particle and waste removal. To clean the interior sponge, you can simply turn the cleaning handle, reducing the need for disassembling, and making maintaining your pond pump easier. 

A maximum flow rate of 6,000L/hour makes it suitable for ponds up to 5,000L in volume – which should cover most garden ponds. The pressurised filter also allows water to run uphill, for a maximum of 3m, giving you greater flexibility in your set up.

This is our most expensive pond pump, but it’s undoubtedly also one of the best. If you’re looking for a pump with built-in filtration and UV clarification, that can handle larger ponds, this could be worth the investment.

Pros

  • Includes a pump, filter, heavy duty flexible hose, and jubilee clips.
  • Built-in UV light helps prevent algae growth.
  • Comes with a biological and mechanical filter, and choice of coarse or fine foam, for efficient particle removal.
  • Cleaning handle makes it easy to clean the sponge, without disassembling.
  • Maximum flow rate of 6,000L/hour makes it suitable for larger ponds.

Cons

  • Our most expensive pond pump.

Does A Wildlife Pond Need A Pump?

It is usually advisable to use a pump in a man-made wildlife pond, in order to prevent the water from becoming stagnant and full of algae. Pumps will also help to oxygenate your water, which is pretty essential if you want to keep fish in your pond.

However, if you don’t have many, or any, fish in your pond, you may be able to get away without installing a pump. To do this, you need to replicate the way a natural pond would filter the nutrients out of the water. One way of doing this is to add plants to your pond.

Plants such as water lilies, water hyacinth and water lettuce will filter out nutrients in the pond water, preventing algae from absorbing these, and growing out of hand. They will also provide shade from the sun, further inhibiting the algae’s growth.

Similarly, if your pond is in a shaded location, it might fare better without a pump than if it were in a sunny spot. There are other ways you can remove algae from your pond, such as raking it manually, or adding a chemical to the water to discourage algae growth.

Ultimately though, if you want to ensure your man-made pond remains healthy, aerated and with a limited covering of algae, a pond pump is probably the best and easiest solution.

What Size Pond Pump Do You Need?

The size of pond pump you need will depend on a number of factors, most obviously the size of your pond. As a rule, the bigger your pond, the larger and more powerful the pump required.

To calculate the amount of water in your pond, measure the length, width and average depth (in feet), and multiply these together. Multiply your answer by 6.25 to get the volume of your pond in gallons, and multiple this answer by 4.5 to get it in litres.

Once you know the volume of water in your pond, you will be able to determine the necessary flow rate of your pump. Generally speaking, your flow rate per hour will need to be at least half the volume of the pond.

If in doubt, many manufacturers specify both the maximum flow rate of their pump, and the size of pond it can support, to make things easier.
