1. Alagae are plants.
2. Not all plants are restricted to uptake of nitrogen in nitrate form.
The form that nitrogen is "available" is dependent upon the pH of the
growing medium. Ammonium complexes are formed in more acid conditions
(pH<5), nitrates are formed in neutral to slightly basic conditions.
3. Some plant species are unable to utilize nitrates and MUST have
ammonia nitrogen. A good example of this is the blueberry (pH3-5).
Plants that are restricted to acid conditions are more apt to require
ammonium as a nitrogen source.
Consider the pH that your plants are found in. When you adjust the pH,
the form of nitrogen will be converted to either ammonium complexes or
