Blue Cloud Dust Questions

I'm sure this is on here somewhere, but can't seem to find it.



First, is all blue cloud dust the same? I've seen the kind that looks the brand name is blue cloud but I've also seen blue cloud dust made by oxbow, all living things, lixit, etc. Is there a difference?



Also, any ideas on where to order it with the best prices for shipping? I haven't been able to find anyone near me that sells it so ordering online seems to be my only option. Unless the kind that you can buy at petco or whatever is the same stuff.



Thanks!!
