Sodium bentonite is the clay used in kitty litter, it is also used to line koi ponds and legally fill oil wells...it also makes your skin better...

I got mine from a koi store and its the brand Benseal (Baroid Benseal). You can mix in just about any natural medium you want and and as long as there is still 1/3 bentonite (this is as low a ratio as I have gone, very possible you could go lower) it will still stick to the glass. There was no paint involved, my goal was to have as natural a vivarium as possible so I didn't use any GS, silicone, paint ect. The background of this tank was about 1/3 sodium bentonite, 1/3 peat, and 1/3 flourite, with a small amount of leca dust added for color.
