Our pods are shipped in medium bags with a small piece of macro algae for transport. Most of the pods will be clinging to this macro algae on arrival.To assure yourself of the number of pods you have received, take the macro algae in hand and pull it apart. You should see numerous pods buried deeply within the macro. To add the pods to your aquarium or refugium, place the entire macro clump to the tank. If you wish to, you may remove the plant clump after 24 hrs.. The pods will have left the macro in search of a new home in your aquarium.
