Koi Medic Salinity Tester

Salinity Koi Medic Digital


The best tool for determining the salinity levels in your koi pond is the Koi Medic Digital Salinity Tester.
This highly developed tool consistently produces results that are both quick and precise.
Simply dunk the sensor into the water to read the result; it is very simple to use.


You can make sure the water has the ideal amount of salt by using the salinity tester each time you add salt to the water.
Salinity levels must be kept at their ideal levels to protect fish health and get rid of parasites in the water.


The Tester has a lifespan of more than 150 hours and runs on 4 x 1.5v batteries.
Additionally, it saves electricity because it automatically turns off after 15 minutes.


Please be aware:


It is strongly advised against putting a lot of salt into the water at once.
The koi could burn from this.
Additionally, periodically check the water's salinity levels because they can change depending on whether it's rainy or dry outside.
