Substitude?

Rock salt or Kosher salt. As long as it isn't iodized. I assume for freshwater. Or saltwater?
 
Table salt is fine. I see no reason why you have to worry about the iodine concentration.
 
I have used iodized many times and never had any ill results. I usually buy a bag of rock salt from the grocery.
