water acetates are not recoverable, they break into an inorganic metal ion and an organic acetate ion. The metal ion (e.g. calcium, potassium, sodium) will remain in the water, while the acetate ion will continue to biodegrade. In the biodegradation process oxygen is consumed creating an oxygen demand that can harm fish.
