You'll note in his previous post that he in fact does do weekly water
changes. Not 1 single person who doesn't has posted a pic of a reef tank
yet.

Therefore it can't be done. Hmmm. That definitely sounds like the kind of
logic that is used by people that do water changes.

I don't have a reef tank. If you look hard enough on the net you will find
pictures of reef tanks that are sans water changes.
