General hardness

[Mkeuper6361]

I'm thinking about getting some neon tetras but my gh is 120+. Is this safe for the fish???

I just looked at my test kit. It says 60 ppm or less for tetras. We do every other water change with R.O. Water to help with the metals and hardness. Basically half of our well water and half r.o.

Can you tell me mbssampley, what parameters are Kh and Gh meant to fall into, what range is good for a tank that stocks a variety of fish, i check mine and don't know if it's okay or not. Thanks

OK. How should I lower it? Thanks btw
