Salt is ubiquitous. It's in the human body, the water and the animals. Table salt, or sodium chloride, usually contains iodine, potassium and an agent to keep the salt from caking due to humidity. If you purchase non-iodized salt, you won't worry about the iodine, but the caking agent is dangerous to fish. Aquarium salt is also sodium chloride, or NaCL, but doesn't have the additives found in table salt. Marine salt is a different kind of salt altogether and should not be confused with aquarium salt. Marine salt contains buffers that will kill freshwater fish and should only be used to salinate the water in salt water tanks in preparation for fish found in the oceans. LED aquarium lighting works really well for saltwater fish tanks. I find them safer to use and they solve the problem of too much heat.

A therapeutic amount (1 teaspoon per 10 gallons) of salt is sometimes added to the quarantine/hospital tank for fish that have damaged shin or lost a lot of scales. This small amount of salt will help the fish with osmoregulation by helping the fish maintain the salt level in it's blood while the fish's wound heals. Once the wound has healed, I recommended removing all the salt from the aquarium by doing a near 100% water change. Salt does not evaporate, so you must do a water change to remove it.What kind?: use table salt (people salt). It has stuff that is bad for fish. The least expensive way it to get Kosher rock salt. No additives such as Iodine. Or you can get aquarium salt (the easiest but expensive). There is controversy on whether you should use salt for marine tanks. I have had luck but there are things in it that may not be the best for your particular fish. So the less stuff in the salt, the better.Also, you have to make sure to do water changes and not just keep on adding salt to the water, as soon your freshwater tank will be a saltwater tank. I know this is obvious, but I have had even stores complain about freshwater fish dying, only to find out they are adding salt and not changing enough water, so just a “heads-up.”Adding: Do not add in one lump to the tank. You will have pockets of highly concentrated salt until it dissolves. The fish do not know to stay away and you kill some good stuff in the tank. Dissolve the salt in a bucket of dechlorinated water first (especially for rock salt). Add a little at a time through the day, depending on how dilute you have it. It lets the fish adjust and you do not shock the system. My husband was so paranoid (he loves his fish), it took him 4 days to add the salt. That is overkill. You can do it in a day, even in a few hours. If you notice your fish are not reacting well, you may have way too much salt. Again, when in doubt, use less. As you get more experience, you will have a better feel for how much to add and how fast. Caution early is better than trying to save your fish later.
