Unbeknownst to me, I recently purchased 3 pieces of lava rock for a planted aquarium which were used previously in a salt water set up.
The reason I now know is that when moving the rocks around small grains of white coral/marine sand fall out (and there were a few small snails shells).
I have tried shaking them as much as possible in addition to hosing down a couple of times, however invariably there will be some grains left in the porous nature of the rock.
Should I be concerned? I could ditch the rocks however they are probably the nicestt pieces in a collection which took me some time to compile.
