It depends, if you can change 100% of your water without killing off things like sponges growing in your rocks then it won't cause any issues. The bacteria you use on your tank is mostly attached to surfaces, while the water does contain bacteria as well in comparison it's minuscule. Things like pH and temp obviously have to match to minimize effects on livestock but realistically it's a proven approach to treating certain containment.

That said 100% maybe fairly aggressive though, more commonly large water changes in the range of 50-80% are used as a more efficient way of dealing with such issues.
