The result was, it didn’t, and was a complete waste of
time. Still, when I came indoors after my mud bath, my
wife said: “Your skin is soft and smooth, just like a
baby’s bottom.” So perhaps there is something in using
clay in our pond water after all.
This all happened long before drum filters came into
existence in our hobby and since then I have learned
that some clay products can cause problems blocking
the finer drum filter screens.
Some of the benefits of using clay
KOI ABSORB I said earlier that I cannot comment on using clay, so I
have asked Kay of Kusuri Products who produce Kusuri
MINERALS Klay to enlighten us all on the benefits.
IN LARGE Kusuri Klay is a montmorillonite clay which mimics the
QUANTITIES natural mud pond environment where high quality Koi
are traditionally bred and grown on during the summer
FROM THE months. It is a pure mineral and is free of any chemicals,
WATER THEY phosphates and base metals. As Koi absorb minerals in
large quantities from the water they live in, the addition
LIVE IN of Kusuri Klay both helps bone and celluar growth, and
aids mineral availability in the water.

Kusuri Klay was researched for Kusuri in the late 1990s
at Exeter University, which showed that this exclusive
clay removes stress proteins from the digestive tract of
Koi carp, 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%. Effectively you are remineralising the pond to
benefit your Koi’s health.

Kay told me that Kusuri Klay is best added to pond
water on a weekly basis, at a rate of 25 grams per 2,273
litres (500 gallons) of pond water throughout the year at
any temperature. Further information is available on the
Kusuri website.

Koi Net magazine is a supplier of information, so if there
are any other producers of clay who would like to let me
know about their product, email me at:
