I would bet your biofilter sucks in that thing as you are constantly setting it's establishment back every time you "shock" it.
You may have never personally seen any negative effects, but you would if for example you had the exact same tank set up and just did 20% water changes weekly to compare it too.
The article on large water changes likely has accomplished aquarists who do test and calibrate their water before doing a large water change.

Can you please post a reference for your claim? As far as I know, if the salinity doesn't drop below 1.018 or its not left to dry in the sun, the bacteria don't have any effect. I don't see people "drip acclimating" LR before adding to the system.
