Personally, I like to see/read ALL opinions even if just based on personal experience without scientific evidence, especially from experienced reefers. (Each person can then decide which advice to follow based on what information was presented and how it was backed up).
To the OP -- I'm sure I misread what exactly you meant when you said tanks "are completely empty" so you might want to clarify. (I'm assuming rocks and sand still in water and nothing living that you care about but could be wrong).
