Quickly, easily promote the control of parasitic, bacterial, fungal, and viral infestations of your pond fish with Seachem Pond HealthGuard. This easy-to-use liquid lets you safely disinfect your fish, plants, and biological filter.

Seachem® Water Garden Oasis Pond HealthGuard contains no malachite green or other dye-based disinfectants that can discolor pond water, or quaternary disinfectants that foam in pond water. This convenient pond disinfectant/medication is safe for your pond inhabitants and biological filtration when used as directed. 1 liter treats 4,000+ gallons.

Directions
Use 125 mL (half a cup) per 1000 L (250 US gallons) daily until conditions improve. Dispense product widely to avoid localized overdose. Use 125 mL (half a cup) per 2000 L (500 US 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 irregularly shaped ponds (e.g., kidney-shaped), take as many measurements as practical to avoid overestimation and consequent possible overdose. Be sure to account for water displacement by potted plants, rocks, or other decorative materials.

Pond HealthGuard 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 1/4 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 re-dose. If signs of stress are acute, promptly initiate water replacement to dilute product. If uncertain about susceptibility to stress, use 1/4 to 1/2 dose and proceed with caution.

Pond HealthGuard should not be used in conjunction with other treatments. Do not use if copper or zinc are present. Do not use if you've ever used Dimilin in your pond (a 100% water change must be done to remove all traces of Dimilin). Do not use if oxygen levels are depressed or water exceeds 86°F.

In most ponds, product does not persist longer than 24 hours, but may in exceptionally clean water. In such cases, delay re-dosing. Adding HealthGuard to hazy water may cause oxygen depletion. In such situations, be prepared to replace water with oxygenated water. Death or rapid release of gill flukes may cause gill stress with some species.

WARNING: Contains buffered glutaric dialdehyde. Avoid any contact with eyes. In case of eye exposure, promptly wash with copious amounts of water and seek medical attention. For decorative pond use only. Do not use in natural bodies of water. Keep away from children. Do not eat, drink, or get into eyes.
