I believe the 'formula' in Amano tanks is to use the activeated
carbon initially, while the biological filter is establishig itself.  Since
plant nutrient requiremnents at this time are low and water relatively
unstable, you can get most of the benefits of carbon w/o the
(loss of) nutrient concern you raised. I think he only uses the carbon
for the initial week or two of a tanks life.
