1st off, i know almost nothing about keeping saltwater fish and never have had a saltwater aquarium... i only know what i pick up in conversation with my sister, who knows just about everything about salt. so, please excuse my ignorance.
that said, i've heard that table salt (PURE SALT free of additives, no iodine or caking agents) can NOT be used in a saltwater aquarium because it lacks the essential minerals that corals and such need to survive in a reef-type setup... ok, that i understand, but here's the question: can regular salt be used for a FISH ONLY saltwater aquarium, and if not, why not?
