Mr Koizumi Clay 86 | Ultra-Fine Montmorillonite Pond Clay

Mr Koizumi Clay 86 Professional Grade Water Treatment for Koi.

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.
