Message-ID: <9001191605.AA06511@sage.cc.purdue.edu> Date: 19 Jan 90 16:05:28 GMT Sender: daemon@ucbvax.BERKELEY.EDU Lines: 12 I dont understand Albert Thiel's statement that deionized water is better than distilled or reverse osmosis water when it comes to aquarium use! Perhaps the situation is different in marine aquaria, but in freshwater, it is only used to soften tap water. Yes, fish will die if put in pure RO or distilled water, that is why tap water is mixed to give the desired hardness. Vinny.
