bioactive substrate?

[ilovemysnake]

i know NOTHING about it.
so, can you guys tell me about it?
i know it breaks down waste, which is what im looking for.
why? because both snakes tunnel, and do the waste in their tunnels so it's next to impossible to tell when they poo or pee.

im looking for some pro's vs cons.
do i use it just like regular substrate?
is there any species of snake it is not good for?
its fine to use with heating pads?
how well does it hold humidity?

any and all advice would be appreciated. not looking for any negativity.
like i said, i know nothing about it, haha.

thanks in advance!
