MolaKule's statement is not negative, he is just pointing out that the additive pack uses magnesium, the newer additive packs are replacing some magnesium with boron. Both work, Harley has a boron based additive pack for SYN3 and the HD 360 conventional. SYN3 and HD 360 have around 700 ppm magnesium and 300 ppm boron. The Mystic has about 1000 ppm magnesium with almost 0 boron. Two ways to get the same results.
