Good basic information, but I'd say there are some leaps of faith in some of the logic that I have a hard time understanding. For example,

"The Carbonate ions formed will make the Ca++ you are trying to add to your tank get wasted by the useless precipitation of Calcium Carbonate -- the white stuff you are seeing."

and...

"Third, after all the cool Calcium ion chemistry is over, the leftover Acetate ions from the broken-down Vinegar leaves you with free organic Carbon in the water that feeds the bacteria in your tank so that it converts more poisonous Nitrates to NO2 gas (a very good thing)."

It never mentions the fact that Calcium Acetate does nothing to boost alkalinity like Kalk does. Kalk boosts both calcium and alkalinity. It also doesn;t mention what that acetate gets turned into by bacterial metabolism, CO2. What do you think does to the pH.
