I have well water at the place im living right now and everything hes been goin great and no problums. but i will have to eventualy move to a place that has city water, do you think other than chlorine, chloramine, is ther anyting els that could be in the water that could harm the fish? do the miniciple water reseviours use other chrmical producs or anyhtign that you would have to worry about?? I would plan to use a large barrel to delorinate, heat, and run with a carbon filter befor hand, and test pH ect. is that about all you can do? becides RO and then recreating the water all over again haha. jsut curious about what you all do? I kno some add right to the tank from a python for example but i kno here they have been playing around with the reseviours and alot of people who do trhta ahve been losign fish after a water change, so im kidna freakd out. thankyou!
