In this blog, I’ll explain why the top Japanese dealers and hobbyists use Shinsuke Mineral Plus as a mineral supplement to increase the health and shine of their koi fish.

Koi in a Japanese mud pound get a lot of natural minerals, which very often are missing in a concrete pond. These minerals provide better growth, good structure and a healthy immune system!

Let’s start the story at the beginning, when I was a boy in Japan and I would drink water from the tap. Nowadays, like most people, I hardly will drink tap water and choose bottled “mineral” water instead. Why? We drink mineral water not only because it looks healthy, but because we know our body needs the extra minerals.

This is the same reason that Champion Koi breeders add mineral rich clay to their koi care routine that emulates the mud ponds in Niigata, Japan.

You might wonder: How to use koi clay in ponds? Can’t I just throw some average mud in there? I wouldn’t recommend this, as not all clay/mud is created equally. Luckily, you will learn more about the benefits of koi clay for your pond in this article.

What minerals and Koi Health Supplements  are important to my koi fish?

All living animals require five major nutrients –

• Protein, carbohydrates, fats, vitamins, and minerals.

While proteins are building blocks for muscle tissue, carbs are the main source of energy, and fats store the energy, vitamins, and minerals support the function of all of the above. Even though vitamins and minerals are rich in koi food, the food by itself, like our human diets by themselves, are not always sufficient to promote normal growth.

Humans obtain minerals by eating plants, animals, and drinking water where minerals are dissolved from the earth. Koi generally live in a highly sterile environment, far removed from natural sources of minerals like they would have in the wild. Our human bodies cannot produce minerals naturally, and neither can your Koi fish. So, for this reason, your doctor advises you to take a daily multivitamin to supplement your diet. In Niigata, Japan, all the champion breeder’s koi get minerals from the natural clay ponds.

For koi pond water quality improvement, Kodama Koi Garden’s Koi Clay Products and Japanese koi health supplements can help. These products are specifically designed to enhance koi immune systems with minerals, mimicking the benefits of natural environments.

Minerals and vitamins will provide proper function of the metabolism and protect against certain diseases. They are critical to balance and maintain body function for all animals, as they support the function of the heart, metabolism, and building bones/teeth.

Why do koi need minerals in water, when they can get it from food?

Minerals can not be produced internally by animals, so your koi must bring minerals in from outside. This leaves only 2 sources of minerals for your koi – food and water.

Choosing high quality koi food for growth and color does provide much of the valuable minerals that koi fish need. But, water should not be overlooked as it is a very critical source of minerals. We drink mineral water, which has minerals already dissolved. Pond water, most of the times, come from city tap water. where the minerals vary on the source of water. The treatment of water is usually deficient as it is highly filtered and sterilized several times before it reaches your faucet.

Additional Pond Minerals Benefits | How Minerals Make Koi Grow Bigger

Your koi may be in good health in crystal clear water, but that doesn’t necessarily mean the water is healthy – it could still be mineral deficient.

After all, it is very difficult to determine if our koi are getting enough minerals or not, until they start showing signs of poor health.

What koi health problems do minerals prevent?

Lack of minerals in your water could cause the following health problems…

According to a chart of “Demanded quantity of Vitamins and Minerals for carp and its deficiency” (Sato, 1991, NRC 1993), the following are the major issues of Koi due to the lack of minerals:

• Growth defects
• Abnormality of Bone structure
• Low feed efficiency
• Increases of Visceral fat
• Poor appetite
• High mortality rates
• Abnormal swimming
• Cataracts
• Anemia
• Short bodies

In our own testing, the feeding efficiency of our Kodama Koi Food is about 68.4%, which is quite an amazing number already. By adding extra minerals, the feeding efficiency went up to 82.5%!

**feeding efficiency is a measure of efficiency to convert feed mass into increased body mass**

The bottom line is, if koi are not taking enough minerals, they will have health problems. When they have health problems, they do not look beautiful. When they do not look beautiful, we have problems, don’t we?

Commonly asked questions about Koi Clay

Let’s dive into the details on koi clay questions that will help you learn more on the topic!

How do you deliver minerals to koi? How do I use koi clay? What are the dosages?

Koi in nature live in natural lakes. Koi eat worms with Minerals (Clay) at the bottom, which strengthens Koi’s organs and make koi healthy inside and out.

There are three possible ways to assure koi are getting the right minerals.

• • Feed fresh and quality food
  • Change water often
  • Add minerals with clay

Just one of the three will not solve all the problems. I recommend combinations of the three. Make sure your food comes from a trusted brand and is fresh enough. Please change water at least 10-20% a week. And then finally consider adding a Clay product to your koi pond.

How to Use Mineral Plus – Dissolve 5-10g of Mineral Plus/265 gallons of water in a bucket and add the solution to a pond two to three times a week. It may cloud your water a little. If you do not like it, add a little water and make a ball with the Mineral Plus. Put the ball into the final chamber of the filter system.

Note: Water quality is different in each area so please adjust the quantities as needed.

Net 400g  – Treats 10,600 to 21,200 gallons

Mineral Plus or Montmorillonite or Bentonite Clay? Is there a difference?

In my understanding, bentonite clay contains montmorillonite clay. So bentonite clay is not 100% pure clay. Some competing koi clay products uses bentonite clay and claim it is the same and cheap. Finding 100% purity of minerals is rare. It is found in specific locations across the globe and is sometimes named after the location that it was harvested. In the koi world, there are many clay products. Most use Montmorillonite clay as their main ingredients. The clay of course is very rich in minerals. The clay also attracts and absorbs toxic subjects like ammonia to purify water.

DEFINITION FROM WIKIPEDIA – “Montmorillonite is a very soft phyllosilicate mineral that typically forms in microscopic crystals, forming a clay. It is named after Montmorillon in France. Montmorillonite, a member of the Smectite family, is a 2:1 clay, meaning that it has 2 tetrahedral sheets sandwiching a central octahedral sheet. The particles are plate-shaped with an average diameter of approximately 1 micrometre. It is the main constituent of the volcanic ash weathering product, Bentonite. Montmorillonite and Bentonite’s water content is variable and it increases greatly in volume when the absorbs water. Chemically Montmorillonite is hydrated sodium calcium aluminum magnesium silicate hydroxide (Na,Ca)0.33(Al,Mg)2(Si4O10)(OH)2·nH2O. Potassium, iron, and other cations are common substitutes; the exact ratio of cations varies with source. It often occurs intermixed with chlorite, muscovite, illite, cookeite and kaolinite.” Learn more about the difference

Even though this is not a human product, this certain type of clay is so valuable that it has been used by humans to cure common maladies with skin, digestion, etc. for thousands of years.

Every summer, breeders in Japan release and raise koi in mud ponds. You will be amazed how big and beautiful these koi will come out of the mud ponds. The body is big. The color is vibrant. The skin is lustrous. The secret we found was in the clay.

The clay in these mud ponds in Niigata were rich in Montmorillonite clay. In Japan it has been a common practice for koi hobbyists who want their koi to grow healthy and beautiful to add clay to their ponds especially and in the USA it is especially important because these koi are often in artificial liners or concrete ponds.

Among all the clay products, it is natural that there are various grades and purity. When you use the clay products, please use the trusted and proven ones from Japan.

Is it true that clay remove toxins from the water and solve common koi health problems?

Yes! Collectively, these minerals keep the water clean and further help to supply good nutrition.

By dissolving slowly into the water through an ion exchange system and in the same process lowering the levels of less welcome compounds also dissolving into the water, such as decaying organic materials thus minimizing the spread of bacterial diseases.

Koi are moved from house ponds into mud ponds from the beginning of May each year. Why are they moved?

1. To promote koi growth in such a vast surrounding.

2. Avoiding heating too much during summer.

3. Keeping the koi in water that includes many minerals so that the koi skin will be bright.

There are other reasons but we aimed at those above and started to develop new products based on them. We believe that koi feed on zooplankton and phytoplankton, and that plankton naturally contains minerals. One of the strong points of keeping koi in mud ponds is that mud pond water includes plankton, which has plenty of minerals, making it the best environment for koi. What’s more, the minerals from the mud itself, are also very important for koi. On the basis of the above, we aimed to add minerals into pond water, to make pond water the same quality as mud pond water.

We experimented with our Mineral plus at five koi farms and results were excellent. After four to six weeks the SUMI on both Showa and Shiro varieties improved. This was even though we developed Mineral plus not for SUMI, but for it to produce the best environment by improving water quality. In fact, the skin of many of the koi turned out to be brighter and polished once the koi breeder added Mineral Plus into their ponds. We would love for you to use our Mineral plus for making your koi more beautiful.

Shinsuke Mineral Plus is a mixture of natural minerals and trace elements, but it’s most unique by the extra micro minerals.
