The inevitable pH fluctuations of aquaculture pond water
Aquaculture species will usually die quickly if the pH is less than 4 or greater than 11 (Table 1). Most species can tolerate a pH between 6 and 9 fairly well, but they are usually stressed by pH outside this range resulting in less growth and greater susceptibility to disease. The optimum pH for most species is between 7 and 8.5.

Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite's function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form a gel-like structure.
