API® POND STRESS COAT water conditioner acts as a unique water conditioner that replaces the natural slime coating on the skin of your pond fish when it has been damaged by handling, netting, or other forms of stress, and prevents the loss of internal fluids using electrolytes. This product contains Aloe Vera to help heal torn fins and skin wounds, protecting damaged tissue against disease-causing organisms. API POND STRESS COAT water conditioner instantly removes chlorine as it conditions tap water, and should be used when setting up a pond, adding new fish, or changing pond water.
