I make the distilled water myself and it has a 0 reading with my TDS meter. The tap water has a reading of over 300. The only thing might be, that I poured the distilled water into the jar which I make the CS in, without cleaning it out first as I thought this unnecessary. I wouldn't have thought there would be enough particles left to cause a Tyndall effect though...dee
