Hang in there. Over time we are gathering facts upon which a better answer can be made. CUSO4 is an option in the right conditions and I have used it successfully before. The trick is a diluted formulation over a small area and moving the water. Also in some situations dye can help. Best way is to reduce nutrients. P binders can also work in small ponds. All of these require info on the chemical make up (water and dirt tests).
