thanks for your post. do you use that product? do you like it?
in my case the black particles will show up in the toilet bowl after 2 or 3 days of spitting out the oil. And i believe that it does make sense that it might be mold, feeding on bits of food perhaps...So I don't think they're toxins coming out in my op if you see what i mean.
but the ionic thing sounds cool. wish i had a bit more money to get it.
