Nishikoi Clear Waters Dechlorinator is an essential water conditioner for making tap water safe for fish ponds. Chlorine and/or chloramine is added to tap water at source to ensure all possible pathogens are eliminated to ensure the water is safe for human consumption. To fish however, chlorine and chloramines are dangerous and life threatening alien chemicals that must be removed prior to exposure. Left untreated, chlorine will damage the natural slime coat on the fishes skin leaving it open to disease and parasite attack, and further damage is incurred to the sensitive gill structure making it difficult to breath and extract essential oxygen from the water. Nishikoi Clear Waters Dechlorinator instantly makes tap water safe for fish and all other aquatic pond life and also protects and helps recover the fishes natural mucus layer. Always use the appropriate amount of Clear Waters Dechlorinator when adding tap water to the pond, during and after transporting fish and after using any fish disease or parasite treatments. In cases where fish stress is evident or fin damage is visible it is safe to double the dose of Clear Waters Dechlorinator.
