lf magnesium chloride in canada

Brad, if it's M. C. Hexahydrate, you'll want to mix 5cups of it with 3cups Epsom salts into RO and after it's mostly dissolved top it up to 1 US gallon/3785ml
This will last you quite awhile, once your Mag is up where you want it

For dosing go to this Reef Chemistry Calculator and select Randy's Recipes 1 and 2 versions A and B
Don't miss the top window where you add your system volume if you want the calculator to actually work

Even though you have a Calcium Reactor, info on the Recipes is here;
An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System
It'll tell you more about the Mag portion the Recipe

Edit: I didn't realise Randy wrote a separate article just for Mag
Thanks for the link

formula is different when you use calcium reactor.

I just looked into the 10:1 bit
I'm mixing mine 10:6 so there's definately a difference

No idea what the hydration is, just says MgCl on bag. Not sure the data sheet indicated either. Just regular old ice melt. I don't want to dig into the depths of my brain and calculate molecular bonds

Bah, don't worry about the hydrate
I just looked into it. All it means is how much water it contains

I'd say go with your 3 cups of 10:1 for a start
Of course, you'll want to boost your current level as I recall you said it's lowish
