Kusuri Klay is a unique, high purity, Calcium Montmorillonite clay which remineralises water, improves water clarity as well as the colour and lustre of your Koi.

This product was researched for Kusuri in the late 1990’s at Exeter University.

This exclusive clay removes stress proteins from the digestive tract of Koi, caused by food left open to airborne spores of fungi and algae.

By adding an optimum level of 5% Kusuri Klay, digestibility of food can be improved by up to 22%.

Kusuri Foods outperform many other foods on the market today because of this addition.
