Red Sea mag test

[vicanic]

So I bought the red Sea foundations pro multi test kit, and the mag part b came without a dropper cap.

I am going to attempt to return it most likely, but out of curiosity, does anyone know the volume of "5 drops," in case I would like to still attempt to use it?

A "drop" is commonly estimated to be appx. 0.05 mL.
