Table Salt?

[JoolsA2]

What does table salt do in a fresh water aquarium?

I don't know the exact effects of it, but I know you shouldn't use it unless it is non-iodized and contain no additives.

Table salt does much the same thing as "aquarium salt". It works OK for treating ich and otherwise needs to be kept out of your fish tank. Sea salt mixes can be used to make a tank brackish or even to make a tank into a salt water tank but table salt only has sodium chloride in it and is not a thing routinely used for any fish. The fear of iodine in table salt is a bit misplaced because it is present in such very small trace amounts as to not really affect the water in a tank.

What about those chemicals in table salt used as "anti caking agents" though -are they harmful to fish?

They are not harmful in the trace amounts that you will have treating a tank for ich. I keep a table salt box in my fish room because my wife got tired of me stealing the one from her kitchen cabinet when I wanted to do a treatment for ich.
