regarded as the one of the Very Best Salt Tester on the World Market
at anything near this price - and is available now from The East Riding
Koi Co ...
We have been using one of these Refractometers to
check the salt levels within our own tanks and ponds for the past 15
years ... that original model, which has not changed, cost me
personally over £250.00 - so only the price has changed - which of
course now puts these Refractometers within reach of most Koi

NO MORE GUESSING:
So now it is possible for you to add Salt to your
pond water accurately - take the guesswork out of adding too much or
not enough .... think about it no more guessing how much salt to add
to achieve the required saline solution for your Koi ...
The water parameters can change over night - be
aware of this if you don't want to go down to the pond to feed the
fish etc and find that you have a major problem on your hands ..
make it a rule, even if you believe that all is well - to test your
water on a regular basis .. that way you will be alerted to any
changes as they actually happen and be in a position to do something
about it.
