Don - he only does this to wild fish he puts in. I am going to catch a few indigenous minnows that are known to eat mosquito larvae and put them in my fish tank. To properly cleanse the fish of unwanted parasites you would clean them in this salt bath.

Do you know if I can just use ocean saltwater? I live on the Bay here in Tampa. It's like 85% salt, 10% fresh, and 5% "you don't want to know" water...
