Along with allowing more Kalk to dissolve vinegar also lowers the pH a bit without precipitating. Albeit, all that crap that doesn't dissolve is impurities in the Kalk that have precipitated out. Using vinegar allows some of those impurities to be dissolved. Kalk is pretty cool stuff, I haven't dosed it in years, but I'm going to start up again.
