That about it, Albert?
Gobies won't clean it, sifters won't sift it, chemicals may leach it back out, but a quick way to fix is to remove. As an option. If you wanted to fix it quickly. It may or may not appeal to your aesthetic sensibilities, but can and often does fix a particular problem.

Yup, sometimes replacing the sand can be quicker than spending endless time trying to figure out what the problem is and still not find it when the simplest cause is right there in the sand. If it works great, if not, move on. No need to start an argument whether or not the sand is causing the problem in someone else's tank.
Obviously, replacing the sand wouldn't be the first option until everything else has been looked at.
