Please keep in mind 8822 is calcined DE (albeit real small). Calcined DE will hold up MUCH better and in fact is more porous than non-calcined (that's why they calcine it). Many other absorbents are either non-calcined (will turn to mush see optisorb) or fuller's earth (Montmorillonite clay) or Bentonite clay and will turn to mush. If the clay is calcined but not vitrified (turface is vitrified and nearly non-porous) it MIGHT be okay. This is a nutshell of the issue.
