     Since brackish water is simply diluted seawater, my guess is this 
     product is merely sea salt, like marine aquarium keepers use.  I would 
     also venture to guess it is more expensive ;-).  I'd pick up a bag of 
     Instant Ocean and use that instead.
     Sea salt is composed of 84% NaCl (by weight), so you aren't really 
     getting that much less NaCl.  I heartily agree it is superior to rock 
     salt, though, as it has Ca, Mg, K and many other useful ions.
     I am curious what native fish Kudzu is trying to keep.  If they are 
     brackish, why not set up a brackish aquarium and plant Caulerpa?  They 
     can tolerate salinities as "low" as 10% sea water.  The fish will do 
     well there also, up to full strength sea water.
