Smelly tank

[Coralgurl]

Didn't have time to post before I left, but I found only 5 snails (out of 20) - all alive. Made quite a mess of the tank with the sand moving around, so didn't keep at it for long. My radiant wrasse was still sleeping, so stayed away from his area. None of the livestock looked stressed either last night or this morning (the ones that were out). I also didn't see any dead shells from the other snails anywhere....will post mid day results...
