Dangers of high GH/KH on fish?

[schoeplein]

I have a GH and KH are both 14-15. I have dwarf gourami, danios, neon tetras, blue rams, and corys. Read that most of these fish like it best under 12. What are the consequences to fish with stats this high? Everyone seems to be happy...

There's really no danger to those fish. I've kept all of those fish in water that hard for many years. Even the blue rams can adapt to that water quite well in my opinion.
