Formerly known as CrystalClear Dechlorinator.
CrystalClear Vanish Dry Dechlorinator, will immediately remove chlorine that is present in city water supplies.
Chlorine and chloramine are substances added to most city's water supplies to make water safe for human consumption. Chlorine and chloramine are toxic to all pond fish. Left untreated, these substances can thicken gill filaments and cause gill lesions to develop leaving the fish unable to breath.
For best results, apply CrystalClear Dechlorinator to the area of the pond with the most circulation. This will allow the product to be dispersed throughout the entire water column.
