Hi David, 

I use boric acid myself. It's cheap and can even kill roaches! 
Whereas borax is cheap and cleans clothes! Really, either will 
work fine. You won't be using enough to alter any water chemistry. 
An aqueous solution of borax is ~pH 8.5 and boric acid is ~pH 5.1, 
but that's in the % areas. FAQ: boric acid is made from borax and 
sulfuric acid. 
My tank levels commonly read between 0.05 -0.5ppm, and there's 
~0.1ppm in our tap water.
