Pond HealthGuardª is an effective disinfectant to promote the control of parasitic, bacterial, and viral infestations of fish in ponds. Pond HealthGuardª contains no malachite green (or other dye based disinfectants) that can discolor the water or quaternary disinfectants that foam. Used as directed Pond HealthGuardª is safe for fish, plants, and the biological filter.DIRECTIONS: Use 250 mL (1 cup) per 2000 L (500 gallons) daily until conditions improve. Dispense product widely to avoid localized overdose. Use 125 mL (half a cup) per 2000 L (500 gallons) daily for about a week thereafter. To calculate volume, multiply average length by average width by average depth. To obtain Liters measure in meters and multiply by 1000; to obtain gallons measure in feet and multiply by 7.5. To obtain average dimensions of irregular shaped ponds (e.g., kidney), take as many measurements as practical to avoid overestimation and consequent possible overdose. Account for water displacement by potted plants, rocks, or other decorative materials. PRECAUTIONS! Pond HealthGuardª is safe for most fish under most circumstances. Since use of any treatment is not without risk, it should not be used carelessly. For prophylactic purpose, use 1Ú4 dose. If many fish are to be treated, first check for susceptibility to stress with a few fish. If fish show stress (surface breathing or other abnormal behavior), do not redose. If signs of stress are acute, promptly initiate water replacement to dilute product. If uncertain about susceptibility to stress, use 1Ú4 to 1Ú2 dose and proceed with caution. Pond HealthGuardª should not be used in conjunction with other treatments. Do not use if copper or zinc are present. Do not use if Demalin has ever been used (a 100% water change must be done to remove all traces of Demalin). Do not use if oxygen levels are depressed or water exceeds 30 ¡C (86Ê¡F). In most ponds, product does not persist longer than 24 hours, but may in exceptionally clean water. In such cases, redosing should be delayed. In water hazy with phytoplankton or bacteria, rapid death of these organisms may cause oxygen depletion. In such situations, be prepared to replace - UPC: 116261302
