Using the Koi Medic Digital Salinity Tester each time you add salt to the water will ensure that the water levels are made up of exactly the right salt levels.

The maintenance of a balanced salt concentration in the pond is essential for 2 basic reasons:

• Firstly, osmosis takes place if there is a difference in salinity between the fish tissues and the pond. Osmosis is the movement of water from less concentrated to a more concentrated solution through a semi-permeable membrane. Most fish have an internal salt concentration of 1.0% or 10 parts per thousand of salt concentration. This is of a higher salinity than its environment. Thus, water moves from the pond into the fish tissues and has knock on health effects.

• Secondly, the control of the concentration of salt in the water helps to eliminate harmful parasites that affect the health of your fish. Salt concentration from 0.3% to 0.5% (3 to 5 ppt) upsets the osmosis balance of some parasites.

Please note:

It is strongly advised that you do not add salt directly into the water in large amounts. This may burn the koi. Also check the salinity levels of the water regularly as it can be affected by wet or dry weather conditions.
