Hard water high ph

[Flossybean]

Hello there,
My ph is 7.8, my kh is 180 and my gh 250
Do i need to do anything to lower this and if yes what should i do?
Thank you in advance

Unless you want to keep wild caught fishes that come from soft acid water, I would not touch it.

A GH of 250ppm is medium hardness and just about every domestic commercially bred fish will be fine in that. And a pH of 7.8 is fine too.

Thank you, is it fine for corydoras too? I've read they need softer water
Thanks

If you get wild caught Corydoras they would prefer slightly softer water (GH less than 200ppm) and the pH to be around 6.6-7.4 but most Corydoras are captive bred and will be fine in that water.
