VirKon S -
Virkon S Aquatic
Low Foam Tablets have been developed for the Koi
hobbyist and aquatic industry. Not to be confused
with the original Virkon S that is used in the
specific world of human and animal sanitization. It
is especially made as a water sanitizer for use in
the recirculation system only and is effective above
temperatures as low as 4 degrees C. In solutions of
1% it can also be used as a surface sanitizer in
your pond equipment area. Our hands and pond
equipment like nets for example are often one of the
biggest carriers/transferors of viral diseases.
Virkon S Aquatic does not treat the
fish directly but sanitizes the water from all those
nasty bacteria and viruses that seem to lurk about
the pond especially in the Spring and Autumn.
Approximately one 5g tablet will
sanitize 500 gallons (2273 litres) of water. Add the
chosen tablets to 10 litres of fresh water and allow
the tablets to fully dissolve, and the effervescent
effect to cease. Then introduce the dissolved dosage
(tablets must never be added directly into the pond)
into the incoming water column either by way of a
skimmer or settlement tank so that it can be
gradually added to the water as it is filtered. One
of the best ways to do this is to make your own ‘doser’.
This is a very simple piece of kit to make, all you
need is a new clean plastic bucket and then drill a
very small hole in the bottom. Pour in the dissolved
Virkon S Aquatic and let it run slowly into your
incoming water column. Dosing is recommended once a
week, this can be increased to twice a week in the
higher risk KHV/Virus periods of Spring and Autumn.
Please do remember though it is important at the
point of weekly re-dosing that you also perform a 5
to 10% water change at the same time using a
declorinating product and do make sure your
recirculation pump is running the whole while you
are treating the pond.
Always remember to turn off any UV
sterilization system you may have running before
starting this treatment. It can then be safely
turned back on after six to eight hours.
A note of caution there is no point
in trying to dip or bath any specific Koi as Virkon
S Aquatic is a water sanitizer only and will not
treat a fish directly!
