Garlic was another strange one that might have worked out - while not likely curing anything like some think, it does appear to make food more tasty for some fish.
You see folks who use like lemon juice for pH and have not been slapped by Dr. RHF yet for this notion, but the orange squeeze was not even for any comprehensible reason.
Experiment with some stuff. See if you like anything. Put a label on it and sell if if you like it. If you think that the reefing additive companies are doing anything more than this, other than wild claims, I suggest that you reconsider. People might buy pasteurized, concentrated orange supplement to keep their fish from getting Scurvy - BRS will probably do a video on it.
