CrystalClear Vanish will immediately remove chlorine that is present in city water supplies. Chlorine is toxic to fish, and when left untreated, chlorine can cause gill damage and leave fish unable to breathe. Use Vanish when performing water changes or setting up a new pond.
Apply Vanish at the rate prescribed after new pond has been filled. After 20 minutes, pond water will be safe for adding fish and plants.
Established Pond Application Rate
Apply Vanish at the rate prescribed when performing a water change or refilling evaporated water.
For Best Results
When adding Vanish during a water change, it is safest to fill buckets of tap water and apply the correct application for the number of gallons the bucket holds. Stir the water in the bucket and dump treated water into the pond. Apply Vanish to an area of the pond with the most circulation to ensure the product will be dispersed throughout the entire pond.
Product Notices
Vanish only removes chlorine. Do not attempt to use Vanish as a fish medication.
