Buyer’s guide – choose the best pond filters for your need
If you want to purchase the best filters for your pond, it is extremely important to have an idea about the size of the pond. You should check whether the filter has the capacity to clean the amount of water that you have in the pond.
You should also check the health of the water. Some of the filters are capable of only doing mechanical cleaning. So, if you have problems of biological bacteria in your pond that water filter will not be perfect for you.
You should always go for those pond water filters that are energy efficient. It should also have different layers of purification that will ensure that both bigger and smaller size debris can be cleaned from the pond.
Cleaning the filter can be another headache. So, you should purchase those filters only with which maintenance will not be a problem.
How pond filter works?
A pond filter simply uses the nitrogen cycle to purify the water for your pond. Plants as we know removes some nitrate from the pond water. Filtration systems or pond filters are a necessary tool used in the caring of plants, water, and fish in your pond. The work of the pond filter is to control the nitrogen cycle in the pond. The nitrogen cycle takes fish produce which is very toxic and then oxidizes them into a positive nitrate. Technically, the plants will absorb then make use of the nitrate that’s left behind. They also add oxygen to the water in the pond too. If the conditions are kept the same, the process goes on indefinitely. In a pond setting without a pond filtration system, the ammonia produced by the fish would accumulate until it has reached a toxic level which is dangerous to your environment. If the pond is also overpopulated, there will also be a higher amount of ammonia.
All filters used for koi fishes are not built to be the same and each filtration system would either get worse or better for the type of pond you have. In the next segment, we will take a closer look at some of the most important features you need to look out for that will best work for your pond and you.
Filtration StagesEach pond filter can be divided into two parts – mechanical and biological filtration. These two stages of filtration are known to be different when it comes to the operation but they are both required and important ensuring your pond is kept neat.
Biological filtration is a type of situation that involves altering biological waste products like ammonia to keep the water chemistry at a safe level while also killing off microbes that are found in your pond. When it comes to biological filtration, this stage makes use of a media substrate which helps the growth of healthy micro-organism in the filter. These microbes as well convert ammonia which the pond produces as waste into nitrates that then can be used by the plants in your pond. Maintaining a biological filter with beneficial bacteria all the time can lead to colonizing the substrates as well as the rocks which can be found in your pond via microbes that change ammonia.
Another stage of biological filtration involves ultraviolet light to kill all unwanted microbes which involve bacteria and parasites that can spread diseases through your pond.
Mechanical filtration is easier when compared to biological filtration but it is also an important factor you should not overlook. This stage of filtration uses a filter to remove or drive out unwanted particles, algae, and a big chunk of waste found in the pond.
Originally, Mechanical Filtration requires multiple layers of mechanical filters which vary in shapes and sizes so that filtration can go on smoothly without any hassle.
Pond filter types
Generally, there are five types of pond filters available on the market.
- In pond pre-filters
- Pressure Filters
- Waterfall filters
- UV Sterilizers
Some of them have only mechanical or biological purification process. Some others have a combination of the two. So, as per your own requirement, you can choose the best one for you.
In Pond Pre-filters:It can be used for small ponds. It does mainly mechanical filtration. Ponds with a heavy stock of fish should not be cleaned with such filters.
Skimmers:This can be used for ponds of any size. It can do both mechanical and biological filtration of a pond. However, for a heavy amount of biological filtration you may need to add an extra biological filtration kit with it. It helps to collect the bigger size debris on the surface of the pond.
Pressure Filters:It is best for medium or small size ponds. This pond pump filter is a mechanical filter. It can be used along with skimmers. This kind of filter is capable of purifying small debris.
This type of filter can be used for a pond of any size. However, it is best for the medium and the small size of the pond. Biological filtration is done just the best with such filters.
It can be used to clean the green water from medium-sized and small ponds. It can also clean the waterborne bacteria and viruses. If you have a pond with many fish, then this device can come extremely helpful.
Benefits of a Pond filter
The pond filter system is mainly required for those ponds where you have kept fish, turtles, or other water animals. It mainly helps in keeping the water of the pond clean so that the creatures you have kept in the pond can stay safe.
- A pond filter adds beneficial bacteria into a pond. These bacteria destroy the invisible toxins in the water. These bacteria break down the Nitrite and Ammonia in the water. It transforms Nitrite into Nitrate. This nitrate can be absorbed by the plants in the pond. The environment of the pond is improved, and it is good for the fish you have kept in the pond.
- The skimmers can help in cleaning the larger debris on the surface of the water. It collects such kind of debris and then helps it for easy removal. So, this larger size debris doesn’t get a chance to sink down and become decomposed.
- A pressure filter can help a lot to remove the green algae from the water. It makes the water crystal clean that is just the best for the health of the fish inside the pond.
- With the help of UV sterilizers, even the smallest particles inside the pond can be removed. Thus, the water will become crystal clear. The water will be so clear you can see fish inside the water. It increases the beauty of the pond.
Features of a pond filter
- It will depend on different types of pond filters. UV pond filters have the UV sterilizers that have the ability to work down to the microscopic level by cleaning the invisible biological toxins of the water.
- It can have adjustable fountain heads. Some of the pond water filters will also have a magnetic drive.
- The bottom drainage feature can ensure the removal of the debris that falls to the deepest level of the pond. This feature will not allow the debris to be decomposed at that low level.
- Most of the quality pond water filters will have easy maintenance features. The components of the pond filter can be easily removed. At the time, the installation should not take too much time. It will also help in cleaning the water filter easily.
- The back-wash feature is also a crucial feature in the pond water filter. This feature will help in removing the collected debris from the pond easily.
- The presence of mechanical sponges will help in purifying the small components present in the pond water.
How to Know the Ideal Size?Tanks Without Fish
To get the correct size of a rectangular or square tank, without any fish or water in it, you can use this formula:
When it comes to oval tanks or round-shapes tanks, try measuring the diameter then divide it by two. The result is the radius of the tank and when that is done, you can calculate for size with this formula:
If your tank has two depths, to get the size, you have to measure the two depths at separate dimensions. To get the average size of the two tanks, add all the measurements, and divide it by the number you measured the depth. The result would tell you the correct amount of water in gallons that make up the tank.
If the tank is irregularly shaped, you can get the size by gauging the width at a different place on the lid, then add them together and divide the answer by the number of times it took you to gauge the width of the tank. That answer is the size of the gallon you need to be filled up. You can also consider using this step if the tank has different depths.For a Fish Tank with Water Alone
If you own a fountain or waterfall and you decide to use the filter on it, here are the things you’ll need to consider. There are measurements you need to look into:
- The quantity of the tubing’s 90° bends, adapters, fittings, and valves
- The dimension of the tubing
- The width and length of your fountain or waterfall
Maybe you are searching for a tranquil flow, we would advise that you stick to 100 gallons of water every hour. Below is the formula you can use to calculate it appropriately:
If you want to know the total dynamic head pressure, you can make use of this formula:
Just like that of the empty tank, you can’t find the real way to get the size of the sifter which is sufficient for a container with a fish load.
However, users can start by selecting sizes that can function with 5 inches of fish for every 5 gallons. You should also have it in mind that the fish in your tank would grow up and lay eggs so you have to choose a size that will contain them when all that is done.
If you find that hard to do, just purchase large-sized tanks and prepare for them to multiply.
If you are a lover of keeping fish and other water animals in your pond or water garden, then you need to ensure that the water of that pond remains safe and healthy. Using a pond water filter can provide you with the best quality water.
By choosing the best Pond filter system, you will be able to keep the pond crystal clear. It will not only help you to keep the fish, turtles, or other creatures healthy, but the visibility of the pond will make it much more beautiful. You will be able to see the fish playing in the water. Choose the best pond water filter that has both the features of mechanical and biological filtration.
