I will be taking another container and split this between the 2 before making more water to lower the KH and DH, but my question really is: can too much KH and GH be harmful to fish?

We don’t keep Discus, but we do have some interesting fish including a black Ghost Knife and African Butterflies. I know that some fish like a softer water to breed in, but we are not really interested in breeding fish at this time. Also, is it more important to pay attention to the alkalinity for keeping the pH stable, or treat the KH and GH equally?
