Your Fish Are Dying Because of Tap Water. The $5 Fix Nobody Talks About.

If your fish keep dying after water changes and your parameters look fine, the cause is almost certainly chloramine in your tap water. Not a disease. Not your filter. The water itself. This video explains what chloramine is, why it is fundamentally different from chlorine, why standard budget conditioners only partially address it, and the five dollar Vitamin C solution that is documented by the United States Environmental Protection Agency, the United States Department of Agriculture Forest Service, and the San Francisco Public Utilities Commission. We cover exactly what chlorine and chloramine are and why both are lethal to fish at tap water concentrations, why chloramine does not dissipate on standing or boiling the way chlorine does, what sodium thiosulfate conditioners actually do when they encounter chloramine and what they leave behind, the verified chemistry of how ascorbic acid and sodium ascorbate neutralise both compounds through an oxidation-reduction reaction, the critical difference between ascorbic acid and sodium ascorbate and which form is safe for aquarium use, precise dosing from United States Department of Agriculture-referenced figures, three honest limitations including when Seachem Prime remains the better choice, and a complete step-by-step method for your next water change. All information is verified against United States Environmental Protection Agency public documentation on chloramine in drinking water, Centers for Disease Control and Prevention drinking water guidance, United States Department of Agriculture Forest Service San Dimas Technology and Development Center dechlorination research, and Pennsylvania American Water chloramine technical documentation.
