Not familiar with it am old school. Maybe try the sodium carbonate way as long as you are sure you are carrying out the test correctly.

4 mL of Red Sea Foundation B in 47 gallons will only boost alk by 0.2 dKH, which would not reliably be detectable, and may easily be consumed in the time between dosing and testing anyway.

Dose more.
