How deadly is table salt to fish?

Can you get Kosher salt?

 

Are you talking about salt with larger grains? I've seen salt with different grain sizes, but all of them include iodine.

 

It does have the larger crystals but it should not contain iodine.

 

Oh, wow! Man, I told you that I have searched every salt for ingredients and all of them have iodine.

 

I know, I was hoping you might have a Kosher delI there or specialty food store where you could ask for Kosher salt specifically.

 

Most stores carry canning salt or kosher salt, usually a 3 lb. box. These lack any additives. However, iodine is not actually a problem, that's an old belief that has been debunked. The fact is that there is rarely enough iodine in our Freshwater tanks to keep some types of fish healthy. It is the anti-caking agent that can be a problem, however.

I didn't find neither kosher or canned salt, but I found sea salt with iodine. It doesn't say that it includes antI cracking agents. The crystals are much bigger than normal salt. Can I use it?

 

Sea salt will work just fine.
