Vermetid snail mitigation strategies?

[Delphinus]

I guess CBB's are hit and miss because I do have one and he won't go after them. He does a bang up job on any aiptasia that dares raise its head though, so at least there's that.

I actually make the kalk solution as thick as I can make it already. It's not so bad really, I mean ultimately I'm sort of resigned to thinking it's still probably the best bet here for me, but I was just seeing what other ideas other people have. Surely I'm not the only one to have had these things proliferate out of control in their tanks.
