Typically, water treatment plants use about 1 ppm of chloramine. All this hard work and chemistry is important to keep people healthy. But, the same chemicals which keep people safe can be VERY toxic to fish. Adding tap water with chlorine or chloramine to a tank can kill off fish quickly. It can also kill off the bio-filter bacteria that keep your tank healthy and happy. So, this water must be made safe for the fish and tank. How do we do this? There are several common approaches, and their effectiveness varies depending on whether your local water treatment plant uses chlorine or chloramine. If you don't know which your water system uses, ask them. If you don't know who your water supplier is, the American Water Works Association's List of Water Utility Home Pages can help. Most pet fish dealers are familiar with treatment methods for removal of chloramines. 作者: ekips 時間: 2018-10-5 10:55:51
