Iodized Salt?

you will need to raise the temp (speeds up ich life cycle) and up your airiation aswell (warmer water less o2)
 
I use normal table salt (noniodized), but I wouldn't think the iodine would be harmful. Actually, I dose iodine weekly in my tanks for the shrimp. They use iodine when molting and regrowing their exoskeleton. I don't know if salt itself is safe for shrimp though. I use noniodized because I prefer knowing how much iodine I'm putting into my tanks.

Salt and inverts: I've never had red ramshorns and pond snails die off when using salt. If they did, there would be far fewer posts about pesty snails that people can't get rid of. I haven't and would never do a salt treatment with apple snails in my tank. I don't know about shrimp... never did it.
 
Shrimp and snails both can tolerate salt levels used for ich treatment. I use normal old ordinary table salt in my tanks when treatment is used. Its always best if possible to isolate inverts, but if not, they should do ok with the salt and heat treatment. Just add the salt gradually and raise the temp gradually.
 
iodine aside, most conventional salt contains anti-caking agents so that it keeps flowing out of your shaker and doesn't clump or become a solid chunk of salt in the box. Quote from one of the salt mfg websites onwhat additional chemicals are added: "Silico Aluminate, Potassium Iodide, Tri-calcium Phosphate, Magnesium Carbonate, Sodium bicarbonate, and yellow prussiate of soda".

Morton's is a little more spread out, but has additional stuff as well.. http://www.mortonsalt.com/faqs/food_salt_faq.html#q5

I doubt any of those additions is high enough to even register inside your tank much less cause a problem, but why add them when there are so many easy sources of salt that haven't got them.
 
i checked out the msds for one of those anti-caking agents, the silicon-aluminum one. i did the math (forgotten it now though) but basically your tank would have to be filled with a salt/water paste before the anti-caking ingredient reached a toxic level.

here it is (and yes, i'm quoting myself)

it would take 3-5 grams of anti-caking agent (sodium aluminosilicate) per LITER of water before it would kill your fish. i'd imagine you would have to use pounds and pounds of table salt before you reached that level. i'm really not even sure you'd have any water left at that point, just salt paste. not only that, but it's not even soluble in water. it just falls down to the bottom of the tank and sits there.

say anti-caking agents are 2% of the total product when you buy a pound of salt. that's 9 grams of anti-caking stuff, at least the aluminosilicate kind, in a pound of salt. in order to become lethal, a 50g (189 liter) tank would need to have 95 pounds of salt added to it.

2% is the maximum allowable amount of that additive that can be used.

Thanks for the help all, but does anyone have any experience with iodized salt killing fish?

I dosed salt into my tank with malaysian trumpet snails, I don't think anything happened as they still move around fine, but I only dosed 1 tsp in a 10g.

How should I go about removing the salt after the treatment is over?
