I agree. If the water has some sort of contamination a small water change is unlikely to lower the concentrations enough to fix the problem. Of course you dont want big temperature or salinity swings but those are easy enough to match up.
Many reefs are close to the surface and experience salinity changes with rain. It doesn't wipe them out.
