8.5.1.Hydration
Hydrate the dry cysts in natural seawater. Use a transparent conical tank or funnel-shaped container (e.g., glass or plastic cylinder, thick plastic bags formed into the desired shape) and keep the cysts in continuous suspension by aerating from the bottom of the apparatus for one hour.
Upon hydration, the dry cysts which are deflated like bean seeds become round-shaped. Full hydration is necessary to insure that the inner part of the indented dry cyst shell will be completely exposed when the decapsulation solution is added.
