The frozen Calanoid copepods from Reef Scientific is an ordinary fish food that goes through extraordinary amount of preparation to preserve nutritional quality. We’ve never given much thought to how a copepod gets from harvest to the home to be used as fish food but as with Reef Scientific’s ozone generator and presifted chemical media, the RS Calanoid Copepod is not your average frozen fish food. The first thing that struck us about the RS Calanoid is that they put their pods through a process that deactivates the digestive enzymes contained in the gut of the food item. This enzyme is inactive while frozen food is frozen but it starts digesting the food item and degrading the nutrition of it the minute the food is thawed. WE’ve often made up our frozen food for a few days at a time and kept it in the refrigerator for days at a time. Little did we know that our thawed frozen food was losing nutritional value by the day. With the RS Calanoid Copepod the enzyme has been deactivated and the food can be left thawed in refrigeration for up to 14 days. Furthermore, the RS frozen pods are wrapped in a kind of coating which minimizes leakage of nutrients when the food is added to aquarium water. Needless to say, Reef Scientific is very proud of their frozen copepod food and we envy the lucky Brits who have access to this interesting food.
