That's My Point...

...just because a person is "published" doesn't mean that everything they say is "the Gospel." :-)

For example, in a recent article in AFM (May 2000) by Jay Hemdal, p. 46 ff: "Aquarium Myths" "Myth #1 -- Iodized salt is harmful to fish. After selling non-iodized aquarium salt in pet stores for 15 years, I strongly disagreed with the person who first proposed to me that iodized table salt worked just as well as the more expensive "aquarium salt." everyone "knew" that the iodine would kill the fish. I had a difficult time believing this basic tenet of freshwater aquariums was false, but it is. You can safely add the same amount of regular table salt to an aquarium as you would non-iodized aquarium salt."

My opinion: I agree that iodized salt does not harm fish. However, it is the use of a certain anti caking agent that is harmful or even deadly for fish. I think the bad stuff is YPS, Yellow Prussiate of Soda? I think that's what it's called. If your table salt has this stuff on it (so that it won't "clump"), I wouldn't even use it as table salt! It can be deadly to fish. Often, they won't even list this on the label, sometimes they do. There is a safe variety of anti caking agent that is commonly used nowadays, but the lengthy name escapes me. I think I need to track down my chemist friends to get the straight scoop on this. It was posted many times on the JAWS Board, but I don't believe that they archieve the board any more.
