I honestly don't know where some of these goofy ideas come from. People are going along fine, then someone says something on the internet, and all of a sudden everyone is dumping olive oil in their beer. If your processes are working for you, stop looking for evidence to change to something else. In this case, it should be pretty evident whether you accidentally dropped all the calcium out of your wort. If you don't have the signs of it, then chances are it didn't happen. Theoretical is one thing, but if you have actual empirical evidence to the contrary, just believe your own senses.
