How long will my frozen algae last in the refrigerator?

Once defrosted, your algae is good for 7-10 days in the refrigerator.
Looking for an easier way?  Defrost your entire bottle, pour it into individual servings in an ice cube tray and freeze.  Once defrosted, remove the algae cubes and place them in an airtight container for storage in the freezer.  When you are ready to use them, place a cube into water, or your favorite drink or smoothie.
