Common cooking salt ( NOT TABLE SALT) is a very useful addition to a koi keepers 'medical' cabinet as it has
numerous beneficial effects on fish. Not least of these is it's ability to counteract parasitic activity and promote healing.
Some koi keepers have a low level of salt in their ponds permanently, whilst others may add a low level over the winter months to help the fish survive the colder temperatures.
Other uses for salt include high strength anti-parasitic dips, the reduction of ammonia and nitrite poisoning.
