I have lots of dead leaves in my back yard this time of year. At least one of the claims is true, dead leaves will tend to reduce the pH of a tank and some fish like to rummage around in a layer of them.
The wild claims of preventing disease in the tank should be accompanied by statements that it will cure anything from body lice to cancer but that's just my opinion.
