darkfur Posted March 26, 2009 Report Share Posted March 26, 2009 you can check the lime content by dropping a little white vinegar on the rocks. If they fizz (it might just be a few lacklustre bubbles) they contain lime and will raise your pH sooner or later. When I take rocks from the river I like to bring them to the boil in a pot just to kill off any flagellates, leeches, nasties that could be hiding. Oh and dog poo germs. The other option is to rinse them in a potassium permanganate solution, I'm sure you can find lots of info on that by googling it. But that's more useful for things that you can't boil up.
