If the FA is in that shallow water, I doubt that fert. will do much for that. To keep down the deep rooted stuff and to gat a good bloom, I would suggest the high middle number fert. Phosphate is usually all that is needed in most cases. The N2 will just grow more vegetation. If the 10-52-4 is water soluble fert. I would only use about 3 to 4 lbs. per acre. Triple super phosphate after if needed to kick it up a notch.
BTW...what is your hardness/alkalinity?
