Eric's response to me at marine depot:
"As I have mentioned in the past, it changes from batch to batch depending on what is available. Are there any particular products you had in mind? There are a lot of new food products out there, and I try to read the ingredients when I see them but as of yet I fail to see anything particularly new or exciting in most of them. I did a group order of food for our local club, and H2) had a frozen coral food that had good ingredients in it, but again, nothing novel. Just convenient that more and more manufacturers are FINALLY becoming aware of the need and size of coral food products and diversifying a bit."
