Losing battle with aptasia

[Beverly]

Sean,

Have soaked a piece of rock in kalk/RO water for an hour or so trying to kill my snail-eating worm. Killed the bacteria, hitchhiker snails, coralline algae. Worm must not have been in that particular rock, as I did not see it come out. Had to re-cure the rock. Would probably work with aptasia, but you'll be starting the tank all over from scratch.
