lf magnesium chloride in canada

[theokie]

I've been using SafeStep bought at Canadian Tire for the past month with no ill effects, raises my mag like it should, according to the reef calculator I use.

Have mixed up about 100 gallons of water and used it as my salt is a bit low in the Mag area. I change 2 percent, about 6 gallons a day on my system and also use a doser to add a bit extra, don't have my spreadsheet for the exact amount.

I stocked up on 4 bags, just to make sure I make it thru until next winter
