I do not feed my corals anything extra and they seem to be doing quite well. While I do not use a protein skimmer I do have as large as a refugium as I can. I have a deep sand bed, extra live rock, and macro algae growing in there. A couple of hermits and snails for good measure. All natural ocean ingrediants.
One thing I have often contemplated but have never really found the answer to is. What in the ocean does the same a protein skimmer does? Nothing that I can think of.
So, the question was if a protein skimmer is necessary or not. I believe most aquarists would say yes. However, there would be a small minority that would say no.
Actually, there is a developing school of thought that agrees with you, and many people are concerned about over skimming. Also, one member of the board, Reefkprz, I think, was going to experiment with running a skimmer for one week, then off for a week, etc, but I don't know what came of that.
