How to design and construct Koi Pond

how to design and construct koi pond 2019

 A Koi Pond may be referred to as a big fish tank or a pool for Koi. The Koi Pond is constructed in a way that stones or water plants are not found. It's built in a way that anything that could cause harm or hurt the Koi is not present in the pond. Since the Koi may fall prey to other animals that may have access to the Koi Pond, the pond is built to protect the Koi and prevent these animals from moving into the pond. For instance, there are no stairs that could give room for other animals to easily crawl in.

As mentioned earlier, the absence of stones or crushed stones and pebbles helps to protect the Koi. Sometimes, the pond may have a waterfall, and the deepness of the pond is usually about 4-6 ft. deep, but it is sometimes more than this.

Also, a Koi pond may have a waterfall, but these waterfalls are different from the filtration system such as the ones found in crossover or water garden ponds.

For you to see the Koi very clearly without any obstacles, you can use a bubble-less external aeration technology.

The Koi pond has a hydro sieve bottom drain pre-filters and hydro clean pond skimmers that help to carry out mechanical filtering functions. Also, Koi Ponds are micro and biologically filtered with very active hydro beads vortex filters that are very easy to clean.

The Koi ponds get its oxygen from an aeration system that involves the pumping of water with an external pump. So, there's absence of high voltage electrical devices in the pond.

Unlike hybrid ponds, crossover ponds or water garden ponds, Koi Ponds are not part of the landscape but items in the landscape. A Koi pond can be better described as a big fish tank or pool that is created especially for keeping Koi.

What pH Level is Safe for a Koi Pond?

What pH Level is Safe for a Koi Pond?

It is important to keep a safe level of to guarantee the health of your koi. Koi has the ability to survive within a range of pH levels, however, if the pH reaches extreme levels it could lead to stress and eventually death if unchecked.

The pH is the level of acidity or alkalinity of the water which is varied based on chemicals found in the water supply. It needs to be constantly monitored to test and adjust it as needed.

- Maximum Range

For your koi to survive in the pond, the maximum pH range should be between 5.5 and 8.5. Any significant variation from the maximum range could affect your koi immensely and lead to death if left unchecked.

- Optimum Range

Ideally, koi's pH is slightly alkaline with a pH of 7.5. Attaining a pH of 7 is neutral and has no adverse effect on the fish, but the ideal range is between 7.5 and 8.

If the pH drops below 7 then it becomes acidic and toxic for the fish.

- Daily Fluctuations

There is a constant fluctuation the ponds pH level which should be viewed as normal and should not warrant any drastic response. Take pH samples of your pond in the morning and afternoon and record it for a specific number of days. Results less than 1 are a normal and negligible. The main aim is to maintain the pH range of 7 and 8. If the change appears to be over 1 then it could either fall into high alkalinity or acidity which should trigger a prompt response.

Most suitable plants to be used in Koi Ponds

Before making the decision of purchasing plants for your Koi pond, you may want to first of all find out about the plants and know which works for your fish and pond. Getting these plants is quite easy; you can either get it online or at a nursery but your fish come first.

Although the decision for the best fit for your pond may be a bit difficult, there are a variety of species with different advantages and disadvantages. Below are some plant species good for your koi ponds.

- Water Hyacinth

The Water Hyacinth, one of the best plants for a Koi fish pond is a surface plant, usually free-flowing. It can grow in any kind of water, be it shallow or deep waters. They are free living plants, often not requiring attention but can thrive in even the harshest conditions like the northern ends of the United States, including regions closest to the equator.

They are aesthetically attractive, with purple and blue petals that attract pollinators like bees and hummingbirds necessary for their growth. They reproduce easily and tend to overshadow other plants if not removed manually or cut.

The Koi fish find this plant very attractive as they often nibble on it. Because these koi fishes tend to chew on the water Hyacinth, it is necessary to clean your filter(s) periodically to prevent blockage as a result of debris.

- Water Lettuce

The water lettuce is another example of floating plant species. They provide not just shade for the koi but also food and shelter. They also do an excellent job at filtering water thus removing algae and other impurities naturally. They have extensive root systems which make them good for koi ponds as they discard unwanted nutrients and take up all the sunlight, eliminating algae from the pond.

Water lettuce are easy to maintain, thus they grow better in water, few inches deep (about 30 feet) at a temperature of about 66 and 80°F. They often have wide area of coverage, one plant can grow ranging about 3 feet or more. It is capable of growing on every continent but Antartica.

- Water Lily

Just like the water lotus, water lily is another species of floating plants and an excellent choice for koi ponds. However, they are smaller than lotus but possess the ability to thrive in colder waters, even with less sunlight. They grow in a few feet or 6 inches of water with distinctive fragrant flowers. The Koi fish take shelter under the lily buds, feeding on its leaves and roots and lay eggs under the leaves.

- Horsetail

Horsetail is one of the prehistoric plants in existence, having existed for millions of years. It is popularly known as scouring rush and is predominantly the last of its kind. Horsetails thrive in water that is not so deep, growing along water edges.  They perform the function of water filtration and are characterized by tall segments capable of holding water.

They don't overshadow or compete with other plants and can be removed easily if they become too much, without affecting the plant. These plants have deep roots with rhizomes like that of cattails, therefore in order to remove it; you pull up the rhizomes gently. Koi use horsetails for shade. They don't eat them.

- The Water Smartweed

The water Smartweed is a submerged plant that grows down in the water. It is known to thrive anywhere, including soil so long as there is moist. Smartweed have a tendency of growing in thick colonies, attaining a height of about 3feet and capable of excessive growth if not cut.

This therefore makes them a nuisance species but it might interest you to know they have the ability to oxygenate water, thus making them good purifiers, making foods for quails, songbirds and tiny invertebrates. These macro invertebrates now serve as food for the koi, supplying the needed protein. This species produce vibrant, active and oblong flowers during summer and mid-autumn.

- Water Lotus

The species Nelumbo lutea, popularly known as the water lotus is a beautiful aquatic surface plant, usually free living with little or no need for maintenance but with unique conditions. They thrive well in water at a temperature of about 75 to 87°F and depth of 18 inches. They require low humidity and at least 5 hours of sunlight per day.

It is best to give them enough space as some tend to grow about 2 feet long, thus making them a better fit for large koi ponds. You should not feel bad if yours is a smaller pond. Dwarf lotus species are also available. Lotuses do not appeal to Koi for food but they provide shelter in hot months, encouraging local pollinators.

- Eel grass

The eelgrass is referred to as the most submerged oxygenating plant. It is particularly resilient, and cannot easily be browsed or removed by koi or any big fish. Some of their characteristics include its massive growth and the ability to thrive best in deep ponds. This helps their grass-like and wavy leaves shade the koi, providing a form of habitat for it.

Shape, size and Depth of the pond

Before thinking of getting a koi pond, the shape, size and depth of the pond should be put into consideration first. From my experience so far, I can say that a good koi pond should be an estimated 25 ft. in length, 3ft deep and 13 ft. width in order to attain standard. This, however, does not mean we can't have smaller ponds, but it is more advisable to follow this measurement as the outcome on your pond will be indescribable.

To enable you fish at any point in time, it is best, judging from experience to make your width not exceed 4 meters. You can easily check your water volume, being conscious of its pH level. Your pond volume is calculated by multiplying the length, width and depth of the pond by 7.5 per cubic foot. The value is in gallons. Using these values, the volume of your pond is 7313 gallons, an estimated 27,683 liters.

There is always a temptation to cut down on cost and go for a small pond but the result is often detrimental. You incur extra expenses in the future as a result of expansion. Certain people who built small ponds initially still had to do more later on and they spent more. It is wiser to go for a large pond; you have enough space for your koi and even room for future growth.

Don't forget that the comfort and growth of your fish, including the maintenance of your pond come first before any other thing.

Note also that koi fish are not like the goldfish, their survival instincts differ. In the best interest of your Koi, it's advised to focus on the size of your pond, following the appropriate measurement. This keeps your koi healthy and stress free.

Constructing Your Pond

After organizing the way your pond will be, the next thing to do is start working towards the building. The shape of your pond will be a significant determinant in the methods you use for construction.

One thing should be avoided in the construction of Ponds, and that is what people generally refer to as “dead spots,” something that can prevent the adequate flow of water. These spots are to be avoided in order to prevent the amassing of toxins that can lead to health issues.

For fish to grow well regardless of the spot it finds itself in the pond; there is a need for water to flow well and stay oxygenated in order to fight off diseases kept by dead spots. However, it should be pointed out that although this building technique, this method is costly, and it seemingly is not for people who are doing for fun.

In this situation, it is best you adopt the rubber pond liner and digging a hole. Ensure to keep track of the environment and be conscious of challenges that will be explained below

Filtration: Maintenance Of Koi fish In the Pond

There is a need for anyone to possess a koi fish pond that has a drain at the bottom which keeps on gravity feeding movement to the filter. This continual gravity feeding gives room for anaerobic particles; which represents a toxin to the growth of the fish to be released from the pond, at the same time not touching the significant elements in the balanced stage of the filter.

The usage of this feeding method guarantees a consistent water flow, and what this translates to is that your koi are not prone to sickness due to the usage of toxic chemicals talked about earlier. Indeed it is worthy to note that there is a need to have efficient filter technique asides the bottom drain and this filter must consist of the following elements:

* Settling Chambers

The most effective design for a settling chamber is a vortex/whirlpool. This chamber allows water inside at an angle towards the down area of the container; this will cause a swirling motion forcing the larger debris towards the sides.

Once this has been accomplished the debris will find its way down the pond bottom where there is a purge line that directs it into the purpose-built container. This simplifies the process of cleaning as you can get rid of dirt easily. This chamber should be a have a minimum diameter of 40 inches (102 cm) and a depth of 40 inches.

* Mechanical Filtration

This system is designed to clean the water of debris as it makes its way through the filtration medium. For it to effectively filter water, it must be placed directly in the water flow path. A 10 cm cylindrical brush is ideal and should be designed with nylon bristles and steel core.

* Biological Filtration

This method involves the use of nitrifying bacteria to convert harmful nitrite and ammonia into nitrite (less toxic). The amount of these beneficial bacteria must be able to cope with the decomposition in the pond, so as to maintain a proper balance. That’s why you should be wary of overfeeding or overstocking your koi pond.

The first set of materials you should prepare for when you want to construct a pond should be testing kits and filtration system. Check a pond supply around you to have a piece of knowledge on the cost of materials needed prior to the construction of a pond. This is to prevent you from getting shocked in the course of development.

One thing is inarguable about koi fish, and that is the fact that this creature is among the most alluring fishes to have as pets. Due to their long life span, people tend to have affection for them as pets.

Hence, failure to care for them adequately will result in the death of this beautiful pet. With this guide, it is believed that you now have a good understanding of how to nurture koi fish and ways to ensure their sustainability.
