F.O.K. - Formulated Clay
After a period of time, harmful bacteria and pond weeds will
often grow in the pond water or in the mud at the bottom of fish
ponds. These harmful bacteria and weeds normally affect the water
quality and oxygen levels in the water. As bacteria levels increase
they can have an adverse effect on fins, skin and general health of
the Koi. All of this is compounded by the daily excrement of natural
fish waste further adding to the imbalance of good water quality.
Scientific research has highlighted that this special clay material
will naturally encourage the growth of "beneficial
bacteria" which will eradicate high levels of these less
desirable bacteria and reduce growth of the pond weeds.
So it is not difficult to recognise, without regular maintenance the
water environment will quickly deteriorate and fish will suffer from
poor health, poor appetite, disease and slow growth.
