One approach called the Belize method selects a carbohydrate addition rate that corresponds to the amount of protein in the feed, i.e., the nitrogen input. The logic of the approach is to eliminate ammonia via assimilation to biomass rather than oxidation to nitrate.

If one were to refigure a dosing formula for large tanks, would it make more sense to scale it to volume, current tested parameters of N&P, or to food inputs - like scrubbers do with the screen area proportional to #of cubes fed daily?
