Barley hay, when it decomposes, supposedly releases an enzyme that breaks the cellular wall of certain species of algae. Note the word 'certain'. I, personally have not seen any positive results from its use. And you have to keep in mind that, when it decomposes, it adds MORE nutrients to the water column.
Where in NW Florida are you? I am in P'cola.
