When you design your home, it is always nice to bring some water life into your design.
You may include it as part of your interior decor or incorporated it into your landscaping.
All in all, it brings a stunningly Zen factor into space. If you have been to any room with an aquarium or a fish pond, there is an overwhelming feeling of relaxation and a transcending emotion of freshness.
Water, the element itself, represents fluidity, and in some cultures, it’s springs of life. We know that water is life, but now try to incorporate it with some living creatures called the koi fish. You will be amazed by the outcome.
The koi fish is a sight to behold. The fish has vibrant hues of yellows, oranges, blues, blacks, purples, and white colors gorgeously patterned on the fish scales. Some fish like the black or the red in the Chinese culture symbolizes and attracts wealth and success.
While in Japan, they are considered a great attractor of good fortune, perseverance, and plentifulness. The Buddhists consider them a sign of courage. And this is just half of it.
Here is the more profound explanation of Koi’s aesthetics and cultural benefits; however, our focus is on the best koi pond filter systems. And here are some of the extra details and facts you need to know about what a koi pond should have.
Features of Koi Pond
A deep, spacious pond
The koi fish, when provided the best environment, grow and multiply pretty fast. And so, the space they are provided for must be at least three feet deep and wide.
The water volume should also be at least fifty gallons. This space gives them ample room to swim and even set the ground for mating and laying eggs.
If you have young koi fish or a species that does not become gigantic, a thirty-gallon aquarium will do just fine.
This is what catches all the solid waste in the pond. The skimmer catches things like uneaten food, pollen, dirt, twigs, leaves, and other floating dirt.
This component usually has a collecting basket where all the collected dirt is removed from this point. If you want your pond to remain free of floating debris, it is best to empty the skimmer often.
A drain at the bottom
Although bottom drains are not a must in typical garden ponds, a koi fish pond sure does need one. This drain allows a fresh stream of water to run through the pond giving the fish an optimal home to live in.
UV light pushed for algae to grow and clamp together. When this happens, it makes it easier for the mechanical filter to clean the pond. When you combine this with an UltraViolet purifier, the water’s lingering bacteria will be killed.
Pumps, water, and air
A koi pond also requires two kinds of pumps to bring in the fresh air and freshwater. This ensures that, even if there are filters in place, the water and the air in the pool are optimized to uphold the fish’s survival.
Clean aqua and purified air will decrease the washing of the sieves we are to look at next.
A mechanical filter
This filter works to pin down the big solid particles and restrict them from infiltrating the biofilter, which can be delicate. To best take heed of these filters is cleaning them often to remove all the stuck objects so that a koi pond filter in the next cleansing stage is not affected.
A biological filter
This is yet another kind of filter that serves to clean the microscopic dirt in th water. It turns the waste from the fish, which is nitrogenous, into the air that is breathable to the fish.
Proper care and cleansing of the biofilter are quintessential as it may be the defining factor that keeps your koi fish alive and flourishing.
There are several types of biofilters, and some are a bead filter, a cross-flow filter, a sand filter, a Bakki shower, and a moving bed filter. The following devices have been selected as the best koi pond filtration system set up to keep your pool clean and the fish in good physical condition.

Koi Pond Filters FAQ
Can you over filter a koi pond?
There is no possible way to over filter a koi pond unless you are using chemicals, which is highly discouraged. The cleaner the water, the better the fish does. Crystal clear water might be too optimized as their natural habitats do not have the same level of clarity, ensuring the aquatic animals have the best.
A koi pond filter that clears off all the green-hues algae makes the water safer for the koi fish hence the best koi pond filtration system setup.
What size filter do I need for my koi pond?
The size of the filter to use for your koi plant will depend on a few factors. The first is the size of the pond, which includes the width and depth. Admittedly, the bigger the pool, the bigger the filter. But you can use a powerful filter to match up the size of the pond.
The next factor is the filter features and, lastly, the gallon quantity of the pool. The rule when it comes to the water quantity is that you should go for a filter that is one and a half times more than the volume of the pool.
How often should koi pond filters be cleaned?
Before you go ahead cleaning the filter, read the manual, and follow the manufactures directions. From the manual, you will know which parts to clean, which to replace, and most importantly, how to do it.
Regardless, generally speaking, the first time to clean a koi pond filter should take place six weeks after installation. And after that, the cleaning must be done once every fortnight, depending on the filter itself and the pond’s size.
A smaller pond might require longer cleaning session interval, while a bigger one might need more cleaning sessions in a month. It would be best to consider doing a deep cleaning session in the fall where you relocate the fish, drain the pool, and get cleansing the pool floor.
You must avoid scrubbing the sides and the floors but instead, mop and use a vacuum cleaner. You should save most of the existing water as much as you can and preferably return it to the pond after cleaning.
Can Koi pond survive without a filter?
A koi pond requires a filter since the koi fish is very messy, and they excrete quite a lot, which may build up to toxic levels. If you do not clean up the pool using a filter, then the fish might not thrive.
More so, the algae in the water and bacteria, not forgetting debris, will accumulate at the bottom, making the environment not so favorable for the koi fish. The type and size of the koi pond filter will depend on the number of fish, and the pond’s capacity, among other factors.
As seen above, the filters are quite affordable, and so you have no reason not to have a koi pond filter in the fish habitat.
The filtration part of a pond is essential. It is what gives your fish a healthy surrounding to swim in and even mate and multiply happily.
But if you fail to filter the water and initiate a continuation of the nitrogen cycle, your koi fish will soon die, and the pool will remain as just that, a collection of smelly stagnant water!
That said, you should include a koi pond filter if you want your fish to grow bigger and beautiful. As mentioned at the beginning, they have a vibrant color that brightens up any space, so why not give them the best since they offer you their best too.
It’s truly a no-brainer to decide on the best koi pond filtering systems since now you have this piece that gives you three devices and two filtering pads. One pad is even recyclable and costs less. All in all, they both get the job done. Your koi fish deserve a happy clean home; make sure they do get one.
