Simple solution:  Apply a tank mix of Parklink’sPondvilla Pro

PondZilla Pro is a natural catalyst that accelerates chemical treatments by improving penetration.  When mixed with an algaecide or herbicide it speeds the breakdown of dead algae and aquatic plants while stimulating naturally occurring bacteria to fixate nutrients liberated during this process. This complex blend of enzymes, cultures, fungi, and stimulants dissolves the dead algae and aquatic plants on a cellular level, reducing their contribution of nutrients. By accelerating chemical reactions, PondZilla Pro improves copper algaecide performance. This is especially critical in hard water applications when copper solubility and performance is reduced. PondZilla Pro alone does not kill anything.
