The older Balling Light formula does but many people these days just use straight Magnesium chloride (I am one of them) and it works just fine.

And I mix 2 kg of magnesium chloride into 2.5 g (just under 10L)

2 of this, one of that though. Its all about what works for you. And obviously either one will work.
