A Question About CO2 Grade

[Flameangel2000]

Hello fellow reefers!I have a 25 lb. CO2 tank and a calcium reactor my question is does it matter what grade of CO2 I use for dosing the Calcium reactor?I mean whether it's food grade or the one used for welding.Thx for your anticipated response.

The CO2 from a welding supply is perfectly fine, and what I have used :)
