I'll push the post to the limit...isn't "Red Tide" a somewhat unknown bloom that seems to appear when the water becomes stagnant, when the salinity levels rise? Killing everything in its path, and remains uncontrollable ? The moral to the story seems to be...you can enhance fertility, but beware of the consequences if you cross the threshold. To steal a phrase, Keep It Simple Stupid (lol) Mother Nature would prefer you to maintain a solid forage base without chemical reactions.
