It is calcium sand, small round grain. So far no problems, I just use a handfull and mix it with the peat. Mites touching it dry out very fast. There used to be some concern that calcium could cause molting problems but this doesnt seem to be the case. Comes in several colours, pretty nice if you are trying to make an enclosure look "natural"Is this the same as calcium sand? I see some red alerts for reptiles when Googling it. But I am not familiar with it nor whether it is okay for a tarantula.
