alkalinity
 

What is the best way to bring up my alkalinity I am at 6.7 Dkh. Will bumping it up affect any
other perameters.

I've used baking soda and this calculator,

Water change?

There are a variety of produts you can use to raise the alkalinity. Take a read through the calcium, alkalinity, magnesium...etc write up in my signature. I suggest brands, explain dosing procedures, and explain how each parameter effects the other. :)
