What is ammonium bifluoride and when should it be used ...

 · Nitric for - 50%. Sulfuric for magnesium - 25%. Water -25% bifluoride for silicon - 8-16 oz/gal. As you well know, there is a tremendous amount of heat generated during make-up. Extreme caution must be exercised, additions must be made EXTREMELY slowly, as I am sure you are aware.
