Prof. Hutchinson (Ref. 15, p. 41) and others have noted that measuring only the soluble inorganic phosphorus concentration and attempting to correlate this with ecological observations is meaningless because: "At the height of summer there may be a great increase in total phosphorus in the surface waters at times of algal blooms, though soluble phosphate is undetectable.
