You wouldn't happen to know or estimate how many drops of 2% magnascent it would take to compensate for the fluoride in tap water, would you? My guess is 2 drops for about a cup? Sheer guessing on my part.
Sometimes at work I cannot resist an espresso, and the machine is automatically hooked up to tapwater. I don't think the tiny little filter removes fluoride.
Ignorance was bliss before I knew about all this water contamination crap!
