Where to buy Mag flake YYC (magnesium chloride)

[Delphinus]

Couple options ....

I think Danny (Wai's) sells the stuff in bulk. Maybe check with the guys at Concept. If you're ok with mail-order then look at J&L "Schlobster" branded bulk stuff and I think TimT sells bulk as well via oceanfreshaquarium.com.

That said .... this is what I use for Magnesium sulfate (because "$8"): https://www.walmart.ca/en/ip/equate-.../6000101671710

and this is what I use for Magnesium chloride: Sifto Safestep 8300 (sidewalk ice melter)
(per http://www.reefcentral.com/forums/sh....php?t=1761791)

Edit: Looks like what we want up here in Canada is Sifto "Natures Power" ice melter: https://www.homedepot.ca/en/home/p.s...000841063.html
Data sheet says 100% Mg Cl Hex: https://www.siftosafestep.com/sites/...chloride_6.pdf
