Crushed corals is perfect for what you are asking for, either mix it in your substrate or put some in your filter.

I like to use baking soda to raise my aquariums' alkalinity.  Needs to be dosed carefully though.  📊

I played around a little with adding both baking soda to raise the KH and vinegar to lower the ph in the new water before I added it to tank. It seemed to work ok but I need to experiment more with it. Coral works unless you're trying to do a soft water lower PH tank.
