I understood, I wanted him to clarify for future generations.You can add borates to your pool water by one of two means - either you add borax (sodium tetraborate decahydrate) OR you add boric acid. Borax is a strong base and will raise pH very quickly so you must add a corresponding amount of acid (muriatic acid) to keep the pH stable. 1 mol of borax requires 2 mols of acid to keep the pH stable. Boric acid, by contrast, is a weak acid and so you can add it directly to your pool and the pH will change very little (about 0.3 units for every 50ppm B you add). Most people find adding boric acid much easier (just don't do what @cowboycasey did ... or else you'll need to buy a change of underwear with the baking soda and washing soda needed to rebalance the water).
To to lock this in perpetuity:
The best way to add Borates to your pool is with GRANULAR Boric Acid, not Borax Mule Team 20, because you do not need to add acid.
If you decide to use Borax [sodium tetraborate decahydrate] (typically in the form of Borax Mule Team 20), you will have to add MA to keep the pH stable.
I, like you, run my borates ~60-70 and love it.
