I am moving, along with my fish of course, and was wondering about the water situation. I am keeping jack dempseys and was using well water which was pretty hard, but I did move them with that water and was wondering about when I go to do next water change with tap water what will be the best approach? I thought that I will slowly adjust them to it but what should i watch out for and will i need to add de chlorinator right away or should it be a gradual adjustment? just looking for some basic advice, thanks
