Bulk Magnesium Chloride in Canada

[whatcaneyedo]

I've been using this road salt for 3 years: http://www.canreef.com/vbulletin/sho...esium+chloride I'm able to buy it from a local hardware store called Amco Wholesale. They used to call it Absolute Zero Meltdown but now its called Safe Step Magnesium Chloride Ice Melter. Its sold in a 50lbs bag for about $30 and I've gone through close to two bags of it while mixing it with Magnesium Sulfate.

I've seen some other people doing this and have always contemplated giving it a try. I don't know though, it just seems like a big risk unless I buy enough testing equipment to know that it really is toxin free. Then I wouldn't be any further ahead anyway.

I think the 'risk' with that kind of product is consistency (or lack thereof). Contaminants might not be present in the bag you have or the next bag but perhaps in the future ? After all, this stuff is meant to spread on the ground so if there's a little spill of something innocuous, who is going to care, right ?

That being said, we all know about the issues with a certain brand of aquarium carbon a little while ago so there are never any iron-clad guarantees but at least with an aquarium product you have a reasonable expectation of it being safe on an on-going basis.
