There is nothing specific in the industrial grade CO2 that your tank needs or conversely something that is missing from the food grade that I am aware of? One is 99.9% pure, while the other is 99%.
The gas is all the same, the impurities come from the type of CO2 tank it comes in. Medical has a glass-lined CO2 tank, not sure about the others.
I use Food Grade from a home brew store, and I've been using it for a decade. Perfectly fine.
