That is a great test - the H202 killed the yeast, but Cs did not.
i have heard CS will kill all bacteria, including our beneficial bacteria - which are darn near essential.
but its not a problem, for several reasons,of which I know only one -
like the bad ones are dying from the CS , and so that leaves room for the good ones to grow, and so if you kill some, it still helps the good ones overall.
I've put H202 on acidophulous, and no bubbling. I figured that meant t was not killing it. NOT TRUE - the bubbling is merely a reaction when metal comes in contact with the H202.The oxidation process [killing] still goes on, and maybe the acidophulous did die, I cannot tell.
BLOOD BUBBLES DUE TO THE IRON IN THE BLOOD.the metal that reacts is the kind that rusts [whats the word for that? FERROUS metals]
