Won't it go naturarly??yes it probably is chlorine i use a little bit of prime when i change water. Prime is a bottle of liqued that you poor into water it removes chlorine and detoxifies ammonia nitrites and nitrates in freshwater and salt water.
do you have a water test kit?
Chlorine gas will go readily. But most of water has chloramine (cheaper and more stable for processing). That being said, you have to let it sit for multiple days and prob there’s still residual. I would buy a bottle of conditioner if you don’t have one.Won't it go naturarly??
