Calcium Montmorillonite clay??
so i read on here its good stuff for scrimpers
calcine montmorillonite clay is 87% the makeup of SafeTSorb..
am i missing something here? its like 6 bux for a 50lb bag
i don't see a lot of people using it except for cheap substrate alternatives?
ARE WE MISSING SOMETHING??
or is it the other 10-13 & crystallized silicates we are avoiding?
