I am a little confused about how to use borax.

Should it be used solely as a pH increaser (in the place of sodium carbonate). Or is there an advantage of having a certain optimal level of barox in the water. e.g. adding x amount to establish a certain level and then adjusting the pH back with muratic acid.

Is there a way (or a need) to test the amount of sodium tetraborate in the water?

In the pool tips, it was recommended to add 1/2 box of borax /10,000 gal starting up..... how big is the box????
