delphine Posted February 4, 2022 Share Posted February 4, 2022 I have some questions about water changes when it comes to dechlorinators. The bottles typically say to add before adding water to the tank but I have seen many filling their tank with water directly from the faucet with a gravel vac. So then when do you add it? And how do you know how much you are adding? I have also heard not to add too much. The measurements are typically so small anyway. How do I work this with my 5 gallon tank? I know this is very basic but I just worry about messing up and then killing the fish. Link to comment Share on other sites More sharing options...
