I think Darryl feeds frozen Mysis, dry flake and pellet, and nori. I could be missing something there too. I agree with him though, my corals have never looked better and I primarily feed frozen Mysis, NLS pellets, a frozen angel diet product, and some nori for my tangs. I gave up dosing oysterfeast, AAs, and the like a long time ago, and things have never looked better. Once digested, these foods are going to essentially feed your reef with AAs anyway, along with other nutrients. I think these products can help reefers with a really low bioload, and who have a nutrient starved reef - that said, lighter skimming, a heavier bioload, or heavier fish feeding will also accomplish the same thing.
