Breeders Secret™ Pond Clay

Breeders Secret is a very pure and natural clay product for your pond. Breeders Secret contains a wealth of minerals and trace elements, most tap water lacks. This natural clay product enhances the pigment cells of your koi and optimizes the quality of their skin like no other product. As the koi absorb the clay minerals from the water, the quality of their slime coat is improved and its protective qualities increased. Minerals and trace elements also contribute to better digestion and support the oxygenation of blood.

Breeders Secret neutralizes bacterial activity and helps bind suspended fine particles. This results in cleaner, more transparent water. In addition it keeps the pipe work clean and reduces film and clogging due to fine particles in the water.

Breeders Secret is drumfilter-proof and will not be flushed to waste.

Suitable for water temperatures of 41 F to 75 F (5-24 C).


You can apply Breeders Secret daily in small amounts or a few times a week in larger doses. When used daily there is only nominally visible clouding despite the constant addition of valuable clay. When used in higher dosages you may observe clouding of the water for several hours afterward. We then advise you to apply Breeders Secret in the evening.

Daily Dosage:
Apply 2 grams daily for each 220 UK gallons (1000 liter) of pond water. Measure the necessary amount and dissolve in a bucket or watering can of (pond) water. Distribute this evenly about the pond.

Weekly Evening Dosage:
1 x 12 grams per 220 UK gallons (1000 liter) of (pond) water or
2 x 6 grams per 220 UK gallons (1000 liter) or
3 x 4 grams per 220 UK gallons (1000 liter)

Breeders Secret cannot be over applied. Over application will result in nothing more than temporary clouding of the pond water which will disappear naturally within several hour/days.

Breeders Secret and Salt.
Breeders Secret can be applied in combination with salt up to salinity of 0.03%.

Breeders Secret and UV.
The working of Breeders Secret is not affected by UV light. Switching off your UV light is not necessary.

Breeders Secret and Medication:
We do not recommend the usage of Breeders Secret in combination with medication in order to avoid any effect of our product on the medication. A large post-treatment dosage of Breeders Secret may help clear your pond of any remaining impurities or medication residues.

Breeders Secret and Water Temperature:
Breeders Secret can be applied at temperatures between 41 F and 75 F (5°C and 24°C).

Breeders Secret is a pure and natural product, safe for man and animals. Avoid breathing dust as it may cause airway irritation. By contact with the eyes, flush with clean water. When swallowed, drink water.

Breeders Secret is available in bags of 2 or 5 kilo.
