pond you are adding chlorine to it and putting your fish at
equipment used to remove chlorine from water is called a
dechlorinator. In simple terms a dechlorinator works by
passing water through activated carbon and out into the pond
providing chemically cleaner, chlorine free water.
chlorine content in water varies from area to area and so
there are no hard and fast rules as to how long the carbon
will work before it is exhausted and needs to be changed,
However, the life of the carbon can be prolonged by regularly
back-flushing the unit (this should also be carried out before
use the first time).
should be in contact with the carbon for approximately 4
minutes to enable it to absorb chlorine and any other
impurities. If you know how fast you wish to fill your system
you can work out what size dechlorinator to buy. Larger units
contain more carbon and retain the water longer therefore
enabling you to fill your pond faster.
The larger the unit the faster the fill.

is easy, all you have to do is make sure that you change the
carbon annually and the pre-filter element when necessary.

refills are available from The East Riding Koi Co direct to your

Today it really is not worth taking
the risk - these dechlorination units are modestly priced to make
them accessible for most Koi and serious pond keepers .. and even
the largest in the range of these dechlorination units is only the
price of a nice koi ... but you can be sure that your water
will be far better than any pond that has fresh chlorine
If these dechlorination units are
not possible for you to buy at the moment then dechlorinators can
be purchased from us in liquid form and it is very easy to add
that to the water in your pond .. see water treatments for
information on those products ..
