Maintaining stable water parameters is the cornerstone of successful Koi keeping. Consequently, the Mr Koizumi GH/KH Buffer provides the essential minerals your pond needs to thrive. Specifically, KH (Carbonate Hardness) acts as a vital buffer for your pH levels. Without enough KH, your pond risks a dangerous “pH crash.” These events happen suddenly and can be fatal to your entire fish collection. Therefore, using this high-quality buffer ensures your fish remain safe from sudden acidity changes.

Furthermore, GH (General Hardness) supports the critical biological functions of your Koi. It aids in osmoregulation and supports healthy bone development. In addition, your beneficial filter bacteria consume carbonates as they process nitrogenous waste. For a deeper look at these essential cycles, visit our Foundational Water Quality Guide.

Preventing Dangerous pH Crashes

A pH crash occurs when the KH in your water is completely depleted. Because rain is naturally acidic, it often strips the KH from your pond water. Similarly, the natural biological processes in your filter consume these minerals daily. By regularly adding Mr Koizumi GH/KH Buffer, you provide a safety net. This constant supply of carbonates prevents the pH from swinging wildly. Ultimately, a stable pH leads to lower stress levels for your Koi and better overall health.

Supporting Biological Filtration Efficiency

Your filtration systems require more than just oxygen to work. Specifically, the bacteria inside your filter need a steady supply of carbonates to process ammonia. If your KH levels drop too low, your biological cycle can stall. Therefore, adding this buffer directly supports the performance of your biological Filter. Using this professional-grade mineral blend ensures your water remains safe and your bacteria stay active.

How to Use Mr Koizumi GH/KH Buffer for Best Results

Using Mr Koizumi GH/KH Buffer is a straightforward process for any pond owner. You simply monitor your levels with a reliable test kit and add the buffer to reach your target parameters. This refined formula dissolves effectively in the water column. Because it is a professional-grade product, it does not cloud the water like lower-quality alternatives.

Always use this product during large water changes or after heavy rainfall. Regular testing and buffering provide the ultimate protection for your fish. Invest in Mr Koizumi GH/KH Buffer in 2.5kg or 5kg sizes today to maintain a perfect, stable environment year-round.

First and foremost, transforming your pond into a crystal-clear sanctuary is easier than ever with Mr Koizumi Clay 86. This product was specifically formulated for the serious koi hobbyist who demands excellence. In addition, it is a premium, high-performance water treatment consisting of 86% pure Montmorillonite.

Unlike standard pond clays that can be gritty or difficult to dissolve, Clay 86 is ultra-finely ground to under 50 microns. Consequently, this ensures total dispersion in the water column without leaving unsightly residue or clogging your sensitive Pond Filtration Systems.

The Benefits of Mr Koizumi Clay 86 for Koi Health

Specifically, why should you choose an 86% concentration? This high-grade calcium montmorillonite works through a natural process called ion exchange. As a result, when the clay particles circulate, they act like a magnet for toxins, heavy metals, and floating organic debris. Furthermore, by binding these impurities together, the clay allows your mechanical filter to remove them more efficiently.

In addition to cleaning the water, this “living clay” releases over 60 essential minerals and trace elements back into the environment. Therefore, it mimics the mineral-rich mud ponds of Niigata, Japan. Regular use not only improves water quality but also provides a vital Koi Health Supplement that supports a robust immune system for your fish.

Why Mr Koizumi Clay 86 Montmorillonite Pond Clay is Essential for Water Clarity

Moreover, if you struggle with “dull” or “tea-colored” water, this pond water polisher is the perfect solution. It effectively removes the microscopic suspended solids that cause a yellow or cloudy tint. Consequently, the result is a “sparkle” that enhances the visibility of your fish and the overall aesthetics of your garden feature.

A Drum Filter Safe Water Treatment

One of the biggest challenges for modern pond owners is finding a clay that doesn’t trigger constant cleaning cycles. Because Mr Koizumi Clay 86 is an ultra-fine 50-micron powder, it is completely drum filter safe. In other words, it stays in suspension longer to maximize contact time and passes through fine screens without causing blockages. Therefore, it is fully compatible with all modern Pond Filters.

Enhancing Koi Pigmentation and Skin Lustre

Similarly, the minerals found in our Montmorillonite pond clay are directly absorbed through the fish’s skin and gills. For instance, this process promotes deep, vibrant pigmentation—specifically strengthening the “Shiroji” (white skin). Furthermore, it enhances the “Sumi” (black) and “Hi” (red) markings. Ultimately, your koi will develop a high-gloss “shimmer” reminiscent of prize-winning show specimens.

How to Apply Your Pond Water Polisher and Mineral Supplement

In order to achieve the best results, consistency is key. For this reason, you should follow these simple steps to maintain a healthy environment:

1. Weekly Maintenance: First, add 10g to 20g of Mr Koizumi Clay 86 per 1,000 litres of water.

2. Mixing: Subsequently, always mix the dose in a bucket of pond water to create a “slurry” before adding it to the pond.

3. Distribution: Next, pour the mixture evenly around the perimeter or near the return from your Pond Pump.

4. Observation: Note that the pond will turn milky for 12–24 hours. However, once it clears, the water will be noticeably more transparent.

Expert Feeding Tips for Maximum Mineral Intake

Finally, for an extra boost during the growing season, you can use Clay 86 as a food coating. To do this, lightly dampen your Koi Food and toss it with a small amount of clay. By doing so, you ensure your koi ingest the calcium directly, which aids digestion and reduces waste.

NT Labs Mediclay is recommended for use as a weekly additive to re-mineralize pond water.

It helps control the buildup of organic waste, bacteria, and pollutants that can lead to bacterial infections and compromised fish health.

Additionally, Mediclay stimulates the biological system in favor of beneficial bacteria, aiding in the reduction of algae. It contributes to water clarity, providing a better environment for observing fish.

How to Use:

Mixing the Dose:

Mix the required dose of Mediclay in a clean bucket or watering can with pond water.

Application:

Pour the mixed solution evenly over the surface of the pond or at a filter outlet to ensure even distribution.

Water Clarification:

For water clarification, it’s best to apply Mediclay via the pump or venturi so that it is rapidly mixed with the returning water.

Conjunction with Other Treatments:

Use in conjunction with other NT Labs water treatments, but allow a 48-hour gap after applying an NT Labs Medication before using Mediclay.

Year-Round Use:

Mediclay can be used at any time of the year regardless of water temperature.
It does not alter the water pH.

Do Not:

Use within 48 hours of applying another medication.

Note:

Regular use of Mediclay contributes to maintaining water quality and clarity in the pond.

FAQs:
Q: What is Mediclay?

A: Mediclay is a high-purity montmorillonite clay containing a variety of minerals and trace elements which are beneficial to fish health and water quality and clarity. Montmorillonite clays are produced by the weathering of volcanic ash, and are hence high in minerals.

Q: What does Mediclay do?

A: Weekly additions of Mediclay will re-mineralise your pond water to control the build-up of organic waste. Additionally, Mediclay will clarify the water and encourage the biological filter to perform at its best, reducing the potential for harmful ammonia and nitrite spikes.

It is also widely accepted that the use of montmorillonite clays, such as Mediclay, enhance the skin quality and brightens the colours of fish.

Q: How does Mediclay work?

A: This is a more complicated question than it may appear.

It largely boils down to the negative charge of the clay particles and their size/structure.

Q: How does Mediclay remove toxic substances from the water?

A: As Mediclay particles have a negative chemical (ionic) charge, positively charged ions will be attracted to and will bond with particles of Mediclay.

This doesn’t technically remove these toxic substances, such as heavy metals, ammonia and pesticides, but instead locks them away preventing them from harming fish.

During water changes and filter cleans, the Mediclay will slowly be removed and thus these toxic substances are removed as well.

Q: How often can I use Mediclay?

A: You can use Mediclay as a weekly additive to your pond or sporadically throughout the year when you think your pond needs a bit of a pick-me-up.

The use of Mediclay will never harm your fish, provided you follow the dosage shown on the label.

Q: Can I use Mediclay alongside a medicinal treatment?

 A: Yes, but we recommend you wait two days after applying Mediclay before using a medicinal treatment.

As good as Mediclay is, it doesn’t distinguish between the ‘extra’ particles in the water that we don’t want there and the medications we add on purpose!

Q: Will adding Mediclay alter the pH of my pond?

A: Continued use over an extended time period may raise the pH.

However, this depends on the current pH level of the pond.

If you need a product to adjust the pH, take a look at our KH – Buffer Up instead.

Not only does it have such a high purity level, this clay is mined in Japan.

One of only a few clays on the Koi market that originates from the home of Koi.

The clay is mined in the Yasawagi Mountains, Akita district of Japan which is also home to the famous “Refresh Powder” clay also known as the white magic powder.

JPD Mud Booster consists of 67 minerals that includes 16 essential minerals such as silicic acid, aluminium, calcium, magnesium, sodium, iron and more.

The unique structure is made up of crystal layers that are a nanometer thick.

As a result, there is a huge surface area of 750 m2 per gram.

This surface area allows great absorption of toxins, and binding of organic substances.

As these substances are absorbed and flocculated by the clay, the filter is far more efficient at removing these substances from the water.

The powder is very fine, making it extremely easy to dissolve. Once fully dissolved in the pond, you’ll achieve crystal clear water that looks bright and alive.

Direct benefits of JPD Mud Booster for your pond water:

• Neutralises and stores waste, toxins, metals.
• Binding of organic substances such as algae and colours.
• Accelerated disposal of undesirable substances in your pond.
• Crystal clear water pond with a soft glow.
• Algae growth is largely suppressed by the removal of nutrients that algae thrives on.
• Stabilises the hardness and acidity of your pond water.

Direct benefits of JPD Mud Booster for Your Koi:

• Due to less toxins and added minerals to your pond, skin quality of your koi can improve significantly.
• The addition of key minerals that your water may lack can ensure the improvement of the immune system in the Koi.
• Improvement in digestion and better resistance against viruses/disease.
• Trace elements can encourage and increase the healing capability of damaged koi.
• Notably better sumi development with the addition of calcium, magnesium and silicates into the water.
• Increased appetite, more confident koi.

Directions:

Firstly, being a natural product this clay is impossible to overdose.

If dosing to the pond directly, it is advised to turn the U.V. off for 24 hours.

Dosage: 

Assuming a water change of 10% per week.

Use 10 grams to every 1000 litres of pond water. e.g. For a 5000 litre pond, add 50 grams of clay.

Dose every 2 to 4 weeks.

If you change more water, then increase the dose frequency.

Add to a clean bucket/container of pond water, stir, and distribute around the pond.

And/Or

Sprinkle or mix the clay into your Koi food and treats.

Initially the Koi may turn away from the food, but with a bit of patience they’ll familiarise themselves to the new taste.
