A mind opener.

As far as I know, iodine remains a non-issue despite the popular belief that it is dangerous to the fish. The concentration of iodine in the table salt is not high enough to harm the fish.

On the other hand, this is a bit intriguing since I cannot for the life of me comprehend whether the aquarium lights may act similarly to sunlight which is the concern also shared by some goldfish enthusiasts when I bumped into this article. Perhaps the lack of exposure to sunlight may not exactly make the salt containing yellow prussiate as dangerous if done in darkened tanks than in tubs or ponds exposed to direct sunlight. It would be much better to avoid salt containing this ingredient though if possible.
Concerns are also being raised about the use of water softener salt to treat fish. Although it does not contain iodine, this kind of salt often contains anti-caking agents that prevent the salt from sticking and clumping together once it is exposed to humidity. One common anti-caking agent is yellow prussiate of soda (sodium ferrocyanide) When yellow prussiate of soda is exposed to sunlight, it generates hydrogen cyanide, which is considered highly toxic to fish. Having said this, I must add that many hobbyists have used water softener salt containing yellow prussiate of soda without causing ill effect to their fish. Just the same, it would be more prudent to use other forms of salt if they are at all available.

Okay, I had a discussion with someone else who is into aquatic gardening in AC. I had him distinguished the difference between aquarium lighting and sunlight. Sunlight has a broader range of spectrum which includes ultraviolet rays. This may be the one likely culprit to cause yellow prussiate to generate hydrogen cyanide. His suspicion was shared by a goldfish enthusiast who pointed the same spectrum that may cause such chemical reaction. Nevertheless, it is indeed more prudent to avoid it and use other salts that do not have yellow prussiate.

I am totally surprised by the Info there. I have worked at four different Tropical fish stores back in the 70's, & The 80's . At all 4 stores we kept a teaspoon per gal. of aquarium salt in all the fresh water tanks except on scaleless fish like eels, knives, & the baby whale. There we did a teaspoon per 25 gal's. The salt plus 80 degree "F" stores overhead heaters made these stores Ich free zones. Our feeder goldfish would come in all dry scaled, & thin. The salt built up their slime coats helprd in getting there appetites back. I was taught slime coated fish are much healthy than dry un-slimy fish. If our Scats, Mono's, Molly's got fin rot i would put them in a saltwater tank.
