I think you need to add all kinds of natural plankton to have a successful tank. I know most people do not live near a beach but I just came back from a muddy beach In New York to collect some food at low tide. Here the tide goes down about 8' and the beach is full of rocks. Under the rocks are loaded with plankton, amphipods, copepods, shrimp, worms and all sorts of food. I swirl these rocks in a bucket then get rid of most of the mud and dump the entire thing (except for the crabs) in my reef. I have been doing this as long as I have a reef and I never had any problems, disease or otherwise. I think this stuff should be collected and sold. It's not like it is endangered or anything.
