I've never used Bentonite clay for pools either but I have in the 
past used significant quantities of clay kitty litter, though 
somewhat fewer than gazillions of tonnes. I now use wood stove 
pellets as kitty litter; they are compostable, cheaper than clay, 
have a pleasurable odour, and the felines have not complained. I 
don't think I should recommend using pellets for pools however. Peter
