To pre-hydrate bentonite for use in fresh water, first add the desired amount of bentonite to a container of fresh water and stir until the bentonite is fully dispersed. Allow the mixture to stand for approximately 15 minutes, stirring occasionally. The bentonite will absorb water and swell, forming a gel-like mass.
