My Oscars have fungus. I have treated with meds and salt. My question is how often do I add salt after the first treatment. Thanks.

i believe its with every water change but i could be wrong wait for some of the other members to chime in

initial treatment of salt is based on the tank capacity...succeeding treatment should
be based on what was replaced only, otherwise, your tank will become salt toxic.
salt never evaporate, whatever water was remove correspond to salt removal too.
