Disinfection and Chemicals

As part of the treatment process, BJWSA adds a disinfectant to drinking water. This disinfectant, chloramines, makes water safe for human consumption. Chloramines are toxic to fish and some other aquatic animals. If you use tap water for your aquarium or fish pond, the water must be treated to remove the chloramines. Local pet stores sell many treatments, dechlorinators, and conditioners. Some remove only chlorine. Some remove chlorine and chloramines. Some don’t mention either. Be sure to read the label and verify that the product removes chloramines.

BJWSA water temperature varies seasonally. The temperature difference between tap water and your aquarium may shock the fish. Be sure to let water reach ambient temperature before adding it to your aquarium or pond. Let new fish acclimate in the bag before releasing them.
