Aquarists Can Use Three
Most aquarists use tap water for their aquariums. This is both for the initial fill up and to top off the tank to replace water lost due to evaporation. If your tap water comes from a private water system that uses a private well for its source, in all probability the water will come from a well which will not be treated with chlorine or chloramine before being distributed to the end-users. Chlorine has been added to drinking water supplies for years to kill bacteria. Chylamine has also been used in place of chlorine because it tends to stay stable and not break down over a short period of time. Chorine can be removed from tap water by either leaving the water open to the air for a long period or using a chemical dechlorinating product. However, choose carefully, because not all tap water conditioners or dechlorinators are the same. The simplest solution to this problem is to buy three-in-one chlorine, chloramines, and ammonia treatment tap water or conditioner. . . .
