Message-ID: <3973@quanta.eng.ohio-state.edu> Date: 19 Jan 90 16:51:42 GMT References: <9001191605.AA06511@sage.cc.purdue.edu> Sender: news@quanta.eng.ohio-state.edu Organization: Ohio State University Lines: 7 Perhaps Albert is a little strong in his statement about the superiority of deionized water. I haven't read the context in which he made that statement, so I don't really know. Deionized water has "zip" metal ions in it. Not all distilled or RO water has so little metal impurity. I doubt if whatever levels are present in distilled or RO present a problem for the aquarist, however. John
