Is there any problem with using well water for bettas and cories? I'm currently using the tap water while I'm at school but in less than two weeks I'm going to be going back home for the summer. I know our water at home is hard and has a bunch of minerals in it but will that hurt the fish?
Also, I can either use the water from the house or from a pipe outside. Both are clean but the water in the house goes through a water softener first. I heard that this was bad for the fish. Is this true?
Regardless of what water I choose to use, how do I condition the fish to the new water? How often should the new water be added and in what amount? I'll be keeping all the water from the fish tank I have set up now and carrying it home in buckets but obviously I have to change it sometime.
