I have 4 tanks with lake Malawi and lake Tanganyika cichlids. I live in town and use city water. It is also ran through the water softener. I know, I know I am committing a sin. But, I can bypass the softener and use straight tap water that it much better suited for the fish. If I was to start using straight tap water that was dechlorinated and heated to the right temp for my water changes, would it mess with the tanks water parameters enough to effect the fish? Would there be a transition period per se?

I have been using tap water that is softened for years. Don't have much of a choice. I don't have problems. I also have a lot of coral in my tanks most of the time.

Lake Malawi cichlids are pretty forgiving with regards to water chemistry. However, high GH and pH is better. Fish from Tanganyika will do much better if GH and pH are close to lake water chemistry.

I have a home made salt recipe for you, will take me a day to find it.
