Keeg Posted August 29, 2021 Share Posted August 29, 2021 So I've lived on underground well water my entire life. The main benefit of this would be that I dont have to add any chemicals or get an expensive machine to make the water safe for fish. But I'm moving into my dorm soon and I'm bringing a tiny tank with me. I do not know how to do a water change with chorine in the water. Can someone explain the process of how to do a water change with choline present. Like do you add the chemicals before or after you add in the new water. Do I have to be cautious of anything? Another question is that the city's water treatment states that they also use ozone in their water treatment process. Is this bad for fish? Do I have to do anything about this? I've been spoiled with well water all my life, never had this issue before. Link to comment Share on other sites More sharing options...
