When I broke down my 75g tank, I fully expected the sandbed to be nasty it had been going for 3 1/2 yrs. To my surprise, once I got below the surface detritus (from removing the rock) the sand was white and full of worms and not very stinky, it just smelled like the ocean.
I wished now that I kept it but it was too late to put in the bowfront and I didn't think I could keep it alive long enough for someone to buy it so out it went for the racoons to play in
