Need to harden water

[Thatfishfreak91]

I'm going to start a cichlid tank I need a way to harden the water

Crushed coral sand?

I agree with Samzter. Crushed coral in either your tank bed, or stuffed in a mesh bag in your filter will increase pH. Adding shells to your tank also can increase pH.

i use aragonite in mine, it looks nicer than crushed coral imo

The coral sand/sea shell method is for freshwater
