CrystalClear Vanish Liquid Dechlorinator will immediately remove chlorine, Chloramine, Ammonia, and heavy metals that are typically present in municipal water supplies. It works effectively to break the chlorine and chloramine bonds (chlorine + ammonia = chloramine) and reduces the chlorine and ammonia down to non-toxic levels. Vanish Liquid Dechlorinator will also add a slime coat protectant to the water to help fish heal wounds and abrasions while protecting them in times of stress (during water changes and clean-outs, for example).
Even low levels of chlorine and chloramines can be extremely toxic to fish. Chlorine is a very powerful oxidizing agent and is toxic to fish at concentrations of less than 0.05 mg/L. Water used for fish culture should not contain any residual chlorine to be considered safe. Chlorine and Chloramines cause gill damage which eventually results in gill lesions. These lesions will eventually thicken the gill filaments leaving the fish unable to utilize oxygen and release carbon dioxide, thus resulting in fish death.
