Has any of guys used the "BSS" for your snakes?

I recall someone had been using it with lizards or frogs, but I forgot who....

I would like to know about how to mix (which materials and the measurements of each material) and how to activate the substrate.

I was planning to try it with my T.a. Atratus that I'll be getting at the Hamm show.

I have a 114 gallon vivarium, with a ground measurement of 8 sq feet.

Would that be big enough for applying this system with 2-3 Atratus?
