Hi, I’m new to aquarium forum. My name is Iryna.
I have cycled 20 gallon tank with two mollies, they doing very good. I want to add new fish some Cory fish and neons. I have very hard water ph 8, KH
143ppm an GH
232ppm, Ammonia and Nitrites 0. I know neons prefer much softer water. Do I have to try to adjust my Ph an Gh
Before adding new fish or neons and Cory will get used to it? I read somewhere that better keep stable water parameters and work with what you have than try to do adjustments and results will be unstable Ph that is not good for fish. Please any advice?
