When it comes to keeping a pet fish, the environment is particularly important. Your fish live in tank or pond water for their entire lives, so keeping them clean is a must.

This is why it is important to find the best pond filters system for your pond and koi carp.

For those planning to start a fish pond business, owning a reliable pond strainer, or what most people would call a fish tank strainer, is a must. This is because tank sieves help not only to keep the water in your tank clean, but also to protect the fish and other organisms within the water from any harmful substances.

And that’s why today, we’re going to share with you a guide to our top picks for tank sieves, how you can know which one to choose, etc.

In this article, we will discuss which are the 10 Best Pond Filters, which exist on the market in 2022.

However, to make sure everyone is on the same page (so to speak), we’ll briefly discuss the function of a pond filter, how it works, when it should be used, and other key question points.


What is a pond filter?

A pond is like an aquarium, but bigger. Like aquariums, to maintain your health and beauty, you need your own filter system.

Pond filter pumps provide the oxygen needed in the water to keep it clean, clear and free of algae. If you don’t have a filtration system in your pond, it is likely to stagnate and draw dirt into the water.

A pond filter consists of a round container. This container has filter materials such as the lid on the top with pipe fittings. There are several types of pond filters which will be discussed later.

Filtration is an essential factor in maintaining a healthy pond. A pond filter is equipped with a filtration system, biological or mechanical, which we will discuss shortly after.

For a pond filter to work, there must be a pump that pushes water through it. The water that passes through the pond filter will be cleaned of any debris, bacteria, fungi or viruses that can damage the health levels of your water and any species or fish that live in it.


Does a pond need a filter?

A natural process in all ponds is the nitrogen cycle. This begins when debris and food scraps sink to the bottom of the pond. Then it becomes ammonia and finally nitrates.

These nitrates are then absorbed by the algae in the water or converted into nitrogen by special bacteria. The nitrogen cycle is essential for the healthy growth of plants and bacteria in water. However, too much ammonia and nitrate are bad for fish.

This is where a good filter comes in. Your filter uses biological filtration, removing these harmful toxins from the water. Therefore, your pond needs a filter to keep the water clean and healthy.

How to choose the right pond filter?

Now that you understand a little better about pond filters, it’s time to make an informed decision. There are a few things to consider carefully before deciding on a pond filter.

Dimensions of the pond

The most important thing to know before choosing a pond filter is the size of your pond. Small ponds are generally 1,000 gallons, medium ponds are 2,000 to 5,000 gallons, and large ponds are larger than that. To find the right volume for your pond, you can use this formula:

Length x Width x Depth = Volume

Take the length of your pond, multiply it by the width and then again by the depth, and you have your volume.

-Former. 4 m. x 5 m. x 2 m. = 40 m. (Cubed)

So you want a filter that can handle 40,000 liters of water.

It is important to note that the result you get is what your filter can handle without fish. When you add fish, you need to double that number and quadruple it when you add koi.

Since koi fish produce more waste and have weaker immune systems than other fish, they need a stronger filter to clean the water extremely well.

Types of filters

You can choose between different filters depending on your style and electrical situation. If you want your filter to stay underwater and hidden, you can choose a submersible filter. These filters stay underwater and are generally quieter.

If you prefer to have your own filter on the ground, you can choose an online filter. For both options, you need a nearby electricity source to connect to. In some cases, how close or far from your electricity source the strength and size of your filter is changing.

Quantity of fish

As this is a pond filter, you need to know how many fish you are expected to have. The density of your pond and the fish in it can affect how the filter works. If you have a lot of fish, even with a small pond, you will need a strong filter.

Some filters come with an estimate of the number of fish the product can filter at one time. For example, some say they can catch up to 30 fish between five and six feet in length.

This is where it is important to get the math right. You want to correctly calculate the number and size of your fish, so that you can purchase the right filter for the job.

UV filter option

You can also search through different features to see which ones you are interested in having. An important feature is the ultraviolet illumination of the filter.

The UV filter is a fluorescent tube that illuminates the pond with UV light. This helps the algae in the water to clump, making it easier for the filter to trap them in the cartridges. You can choose a filter that comes with this lighting attached or one with a separate light for the main filter box.


What is the best pond filter system?

Of all the fantastic pond filter options on this list, the best is hands down the POND BOSS filter kit. This system offers so many great features at a great price too.

The installation and cleaning process is simple and there are full cleaning cartridges. It even comes with innovative fountain heads for when you want to add that extra elegance to your pond.

All in all, this is a great system for fish owners. Whether you’re new to the pet fish scene or a veteran of the sea, this is definitely a pond filter you need to try.


How to install a pond filter and pump?

Installing a pond filter is a very simple and easy process. Some filters may have their own instructions on how to get started, so it’s a good idea to look into them.

Generally, the pond filter is placed on the shore near the pond or submerged. Most people choose to buy submersible filters because they are easy to hide.

Start by adding enough water to your pond so that it completely covers the bottom. Place the filter on the bottom of the pond or on the side depending on what type you have.

Continue filling the pond until it is full. Then connect the pipes to the pump and start running them through them. If you installed it correctly, the water should move freely through the filter.

If you hear sucking or clogging sounds, remove the hoses and reinstall them. Let the filter run all day and night before adding fish or plants. This allows the filter to achieve optimum speed and power so that it works perfectly before adding the fish.


How often should I clean the pond filter?

The pond filter only works well if it is cleaned. If your filter is dirty, it won’t do a good job of keeping your pond clean. There are different types of filters, so even for them there are different cleaning speeds.

Some filters require little or no manual cleaning due to their design. Others need to remove the cartridges from time to time and clean them thoroughly.

Depending on how big and powerful your filter is, you can extend its cleaning to once a year. It all depends on the amount of energy used by the filter and the type of fish and plants in the pond.

If your pond has a significant amount of fish, you will need to clean it more often than in a smaller pond. A wide variety of plants, fish and other animals in and around your pond means cleaning frequently.

A good rule of thumb when thinking about a pond filter cleaning schedule is to make a routine. If you have a lot of fish in your pond, you should clean it once every three to five months. If you don’t have many fish, you can attack them once every six months to make sure the filter is clean.



Finding the Best pond filters from even the top rated pond filters can be difficult due to the large selection. It takes longer to search for the filters you are interested in, but it’s definitely worth it. You can find one that fits your budget and is more suitable for you and your fish.

More importantly, a little extra effort to find a good filter is what it takes to give your fish a happy home. Both you and your fish can enjoy a high quality filter. Your fish can enjoy living in a clean environment and you can enjoy having your fish friend for many years.
