Magnesium chloride

[JOZEFEK]

I found in ACE store Mg Chloride 100%
Melts ice down to -15F/26C
Unique ice-penetrating crystal shape provides rapid melting capabilities and scatter control
100% pure magnesium chloride
Safe for people pets and vegetation when used as directed
Safe when used as directed on air-entrained cold weather concrete that is at least one year old
Less corrosive on metal surfaces
Made with 100% magnesium chloride hexahdrate
Its maximum power melts ice in extremely cold temperatures and with 1/3 less chlorides
It is safer for pets, people and the environment
Extreme 8300 magnesium chloride represents the overall best performing product in the Safe Step line

And was wondering if it is ok to use in Aquarium
THANKS KJ

I do not know if it is adequately pure or not. One concern with some grades of magnesium chloride is ammonia, which is a known substantial impurity in some processes for making it.
