What is a Koi Fish Pond?

 

Koi fish is a Japanese variant of the Amur Carp (Cyprinus rubrofuscus). The fish belongs to the family Cyprinidae that also includes Goldfish.

 

The first known variety of Koi fish was the Narumi Asagi Koi fish bred in the 1800s by fish farmers in Asia.

 

A Koi fish pond has become popular across America and Europe for their mesmerizing array of colours. The pond specifically built to house the fish so that they thrive and display their best color.

 

How to Build a Koi Fish Pond?

 

 

You can buy a standard or above-ground Koi fish pond kit online for building a Koi pond.

 

The benefit of using a kit is that you won’t have to design the pond. You will only have to dig a hole for the installation of the equipment. But using a kit has a disadvantage due to the limited design and size options available.

 

That is why you may want to construct a Koi pond yourself. Here are the steps involved in the DIY construction of a Koi pond.

 

Step 1 – Choose an Appropriate Size

 

Building a Koi fish bond is not that difficult. A Koi fish pond size of 13 feet x 10 feet (3.96 m x 3.04 m) can hold a group of 10 mature fish without being overcrowded.

 

The pond’s width and depth should not exceed 13 feet (3.96 m) and 4 feet (1.22 m), respectively. Its is essential to make it easier for you to catch the fish when changing water or cleaning the pond.

 

If you want to raise the fish, the Koi pond’s depth should be about 8 feet (2.4 m). Beginners and fish enthusiasts avoid the deeper pond

 

Another essential factor of the Koi pond is the volume. Can calculate the required work by multiplying the length, width, and depth of the pond. 

It will give you the volume of the pond in cubic feet or meters. Calculating the pond’s magnitude in gallons multiplies the volume in cubic feet by 7.48 or cubic meters by 264.17. The volume measurement will allow you to determine the amount of water you will require for the pond.

 

Step 2 – Choose an Appropriate Location

 

The next step is to locate the right location for the Koi pond. A good place for the pond is close to the home window so that you can get a clear view of it.

 

Once you have selected the pond’s site, mark the area where you want to build the pond with chalk. You can define the space in whatever shape you desire. The Koi pond can be a polygon, round shape, L-shaped, rectangle, or whatever form that seems suitable to you.

 

Step 3 – Build the Koi Pond

 

Clear the area where you want to build the pond. You may have to remove the vegetation surrounding the area or pull up the paver covering the ground. Now, start digging with a shovel. Dig the pond’s sides, so they slope steadily downwards towards the centre of the pond.

 

Next, line the pond using a rubber or plastic liner. You can buy a pond liner from your local or online landscaping supplier. Should install the liner as per the recommendation of the manufacturer.

 

Roll the liner out over the pond but make sure that it overlaps the edges by about 3 feet (0.91 m). To prevent damage to the liner, remove any sharp stones and rock in the hole before installing it.

 

Secure the liner by placing large rocks over it at the edges. About 1 foot (0.30 meters) of the liner must expose beyond the stones. Dig a ridge around the perimeter once you are happy with the layout of the rocks.

 

You can also use a spade to shift dirt into a ridge formation with the liner reaching into the ridge. The small height will run along the pond’s outline beyond the rocks that will prevent soil, rainwater, grass clippings, and lawn fertilizers from reaching the pond.

 

Step 4 – Add Water

 

After you have built the pond, fill it with water using a garden hose. Use a de-chlorinator, water conditioner, or charcoal filter to add tap water to the pond. It will remove chlorine from the water as chlorinated water can harm your fish.

 

The water should be slightly alkaline with a pH value between 7 and 8.6. You can buy a water testing kit to ensure that the water’s nutrients and pH levels are suitable for the Koi fish. Adjust the water temperature to ensure that the fish stays healthy.

 

The ideal pool temperature should be between 650F – 750F (180C – 240C). Use a thermometer to measure the water temperature. Add cold water if the pond temperature is getting warm. You may want to use a heater if the temperature goes below the freezing point.

 

Your Koi fish can survive in temperatures between 34–90 °F (1–32 °C). But it would help if you kept the water temperature at the recommended setting to ensure that they remain in the best health. Additionally, a change of about 10% of the total volume every week: avoid changing too much water at one time as it will cause the fish to go into a shock that will be fatal for the fish.

 

Step 5 – Koi Fish Pond Setup

 

Dirty water can kill your Koi fish. A filtration system is essential to ensure that the pond water remains clean. A pond filtration system consists of a setline chamber, biological unit, mechanical filtration, and a bottom drain.

 

Should the filtration system be set up next to the Koi pond? You may have to dig the ground slightly to install the individual parts of the filtration. The biological filtration unit will add beneficial bacteria that will reduce the nitrate and ammonia in the water. Moreover, the mechanical filtration part will catch any debris that floats through the water.

 

Consider placing an aerator in the pond that will keep the water moving. It will keep the water from oxygenating the pond and promote the exchange of oxygen. It will also prevent the pond water from freezing during frigid winter months. The aerator should be suitable for the size, shape, and depth of the Koi pond.

 

Step 6 – Place Your Koi Fish

 

Before adding your Koi fish to the pond, you should turn on the aerator and the filtration system. Add the fish in the pond but keep in the plastic bag for about 30 minutes to adjust to change in temperature.

 

Next, add a small amount of pond water in the plastic bag and let the fish float for 30 minutes more. Release the Koi fish in the pond once it has adjusted to the new water conditions.

 

 

 

 

Koi Fish Care Tips

 

Koi pond requires a moderate level of care. You should make sure that the water is kept clean at all times. Additionally, Should also hold parameters at the recommended settings. Use a de-icer to prevent water from becoming frozen during the winters.

If you live in an area that gets extremely cold during the winters, you should consider turning off the pump and the filter. The shallow temperatures will result in the freezing of water inside the pipes. It will result in cracks and damage to the pumps, filter boxes, and pipes.

 

Koi Fish Mates

Small Koi fish feed on flake or small food items, while adults prefer pebble food. You should provide carbohydrate-rich food to adult Koi fish during the mating season that occurs in early spring to late fall.

 

Avoid feeding the fish during the storms as they need oxygen to digest the food. Oxygen levels in the air fall when it rains that is harmful to the fish when feeding.

 

Koi fish also feed on plants. You can plant fanwort and American waterweed in the pond. Moreover, it would help if you planted water lily as it will serve as a cover for the fish from the intense rays of the sunlight during the summers.

 

Wheatgerm is a recommended food product for Koi fish. T carbohydrates and healthy fats.

 

They are particularly recommended during the winters when the digestive system of the fish slows down. But sometimes the fish won’t eat the food. You should keep an eye on the feeding behaviour and adjust accordingly.

 

 

 

 

Common Diseases in a Koi Fish Pond

 

 

Koi fish are a hardy species. But the fish becomes susceptible to parasitic and bacterial infection during the winter season. The cold temperature slows down the bodily functions of the fishy ar, including the digestive system.

 

To prevent diseases, you should treat the water before e the onset of the winter season to ensure that the water remains free of parasites and bacteria.

 

Flukes and internal worms are the most common diseases. You can prevent these diseases by using praziquantel on the online pet store.

 

The medication, when given as per the recommended doses is effective in killing internal and external parasites. You should provide a dose of the medicine before starting the winter season and again at the beginning of the spring season when the fish become active also.
