How can I adjust water pH?
user
If you mean, how can you make water more alkaline, it would be helpful to understand how to define “alkaline”, and what the pH scale is used to measure.  I can give some pointers on this, if you’d like.

Do you mean how can you lower the pH of the water?  A method called “baking soda” will help.  Can I help you with that now?
