also, where the hell are you getting de-ionised water? unless thats the same as distilled water... the only place i've heard the term 'de-ionised water' was in a chem. lab... in just about any drug store you can pick up a gallon of 'distilled' water for a couple bucks or less... its right there with the regular bottled water. anyone know the difference between de-ionised and distilled water?
