Hiya Nikki and welcome to Reef Frontiers. Feeding is very important to our reeefs, mainly because its something we add to our tank every single day so whats in it plays a very large role in the water quality of our tanks. In regards to the shrimp and poofy

, all seafood products we find at the local grocery store are sprayed with a saltspray either right on the boat or at the docks, the spray is used to lock in the moisture and enhance the color of the food, harmless to humans, but the spray is loaded with Phosphates. So if you feed this food to your tank, soaking it in striped ro water will pull the majority of these Phosphates out, then just throw away the water and feed the balance. So it not just shrimp but all seafood.
Now in saying that i still believe seafood is the best thing you can feed your tank. On what is good and what is not, I try to stay away from most bottom dweeler as in clams, oysters also squid of coarse has a nasty ink problem, hehe.
I will give you something to think about when it comes to feed for the reef. Now days a lot of the big push coming from the experts? is to try to cultivate natural food for your tanks. Critters like larvae, rotifers, pods and so on. For me I find those things so inferior to feeding a simple belnded seafood. Heres an example, lets compare say a pod to a simple chunk of shrimp meat. they are both the exact same size and weight. Pod first: the pod is made up of a shell, legs, antenii, and protien meat, now if we strip away all the stuff that is not eatable we are just left with the protien meat inside, maybe 40 to 50% of the total critters mass. Now take the shrimp meat, Hmmm 100% meat and 100 % protien. So in lining them up a simple chunk of shrimp meat gives twice the protien need to whatever feeds on it. Now go a little deeper, if you create an enviroment for the grow and production of these natural food sources (pods/rotifers, larvae and so on) ie the sand bed or the refugium or what ever, you have no control over in population fluxes. They will populate and die off at thier call, not yours. When the die the hurt the water quality for all in the tank. With the seafood mix, you control the input and you control how quickly it goes in, then you also control it removal. I believe it to be a far more efficient and healthy way to feed your corals and all othes in your reef.
On the Cyclop-eeze I beleive its a mixture of deadzooplankton and a variety of other simular products blended into a paste. putting it into your tank naturally stimulates the polyps of most corals and gives the appearence of the coral going wild. I beleive corals that actually do intake prey will feed on it, the only downer I see is that as with all foods like this preservatives must be used in the making of these kinds of foods, or they wouldnt last a week.
