Did you stir the sandbed down to the bottom, if so it could also be methane posioning if you had a deeper, organic loaded sandbed...

Well, I don't know much about that guy's sandbed and his resulting die off. I did not experience any die off when I moved my tanks. My sandbed was about 3". When it was in the pails with a bit of water, yes, it smelled like rotten eggs. The water in the pails was ghastly murky brown which is why I did my best to leave the water in the pail and only remove the sand

Yes, there was a grey ring around the sandbed about halfway down. Yes, when moving the sandbed, I scooped it all up at once, mixing top and bottom and everything inbetween. But, again, I say I had no die off in the tank at all. Surprised even me.
