How can salt be used effectively as treatment of fish?
Whether or not you should even think of using salt in an
aquarium is dependent on the type of fish you keep in it. guppies,
for example, do well with the manufacturer recommended dose of
aquarium salt. Gold fish, on the other hand, need little or no
aquarium salt. while appropriate salt levels will encourage good
health, aquarium salt shouldn't necessarily be used to treat fish
diseases. it might help, but that depends entirely on the
problem.
Also, the right type of salt to use depends on your aquarium. a
marine aquarium requires special salt and readings on the specific
gravity of the water. freshwater and brackish fish are more likely
to require simple aquarium salt. Either way, we aren't talking
about table salt here. go to the pet store and get something
designed to be healthy for your aquatic pets.
