Koi Klay Boost is a high-purity, ultra-fine calcium montmorillonite clay sourced specifically for koi pond use. This mineral-rich clay has been relied on by top Japanese koi breeders for decades to produce koi with superior color, skin quality, and overall vitality.
Designed for modern pond systems, Koi Klay Boost restores essential trace minerals lost to treated tap water and recirculating filtration while improving water clarity and pond balance.
Replenishes Essential Trace Minerals: Restores minerals stripped from tap water and depleted in closed pond systems.
Improves Water Clarity: Binds suspended fines, dissolved organics, and microscopic debris, allowing filtration to remove them more efficiently.
Supports Slime Coat Health: Strengthens the slime coat, the koi’s first line of defense against bacteria, parasites, and environmental stress.
Enhances Overall Pond Environment: Creates a more stable, mineral-balanced system that supports long-term fish health.
Ultra-Fine Calcium Montmorillonite: High-purity clay designed to disperse easily and remain active in pond water.
Japanese Mud-Pond Technology: Based on techniques used by elite Japanese breeders for skin quality, luster, and body condition.
Cold-Weather Friendly: Supports slime coat and mineral balance even when immune function naturally drops in cooler temperatures.
Exceptionally Clean and Pure: zero fillers, zero sodium bentonite, zero additives, and lab-verified for low heavy metals.
Koi Klay Boost is safe for koi and all ornamental pond fish, aquatic plants, and biological filtration systems. It will not disrupt beneficial bacteria when used as part of a normal maintenance routine.
1 cup per 5,000 gallons weekly.
Mix the clay with pond water in a bucket to form a slurry, then distribute evenly around the pond. Water may temporarily cloud as the clay disperses; clarity improves as fines bind and are filtered out. Koi Klay Boost may be used year-round as part of a regular pond maintenance program.
Store in a dry location and keep the container sealed when not in use.
Koi Klay Boost is a high-purity calcium montmorillonite clay, not sodium bentonite.
Temporary clouding is normal and expected. As the clay binds fines and organics, clarity improves.
Yes. It is safe for biological filtration and pond plants.
Yes. Maintaining mineral balance and slime coat quality is especially important in colder water.
No. Koi Klay Boost is a mineral supplement and water conditioner. It supports fish health but does not treat disease.
