CUC Suggestions for 1-2mm "sand"
 

I used 1-2mm grade aragonite in one of my tanks. At the time, I didn't think about how this would affect what CUC members I can use. I could see Nass snails finding it objectionable, as well as Cerith snails. Which is a shame, as I'd like to put both in this tank.

I'm very much on the "nothing with an exoskeleton can be trusted" bandwagon, and I would really prefer to only use snails.

Will the sand I chose be inhospitable to Nass and Ceriths?
