<font size="2" face="Verdana, Helvetica, sans-serif">Alan, is it possible to remove the rock to a separate container? Dry rock from a tub somewhere sounds suspicious. Maybe some lawn fertilizer fell on the rocks in his garage!! If you can put the rock in a separate tub with a heater, etc, it might remove a possible food source for your soup. Far fetched, yes....but it would eliminate a big possibility.
If you saw the sand working, it's most likely fine.
