Colon liver cleanse

Are dense dark brown and black watery stool from the Colon Cleanse a sign you are getting the inner plaque out of fecal matter or is it something else? And do people always eventually pass calcified stones on the liver cleanse? I passed no stones on the 9th flush. Not sure if I have big stones trying to come out or maybe I should of done a more intensive Colon Cleanse even though I take the Oxypowder every other day. Week prior I ate bad and my digestion overall is better but not good yet. Tweet
