Can you use food grade co2 for aquarium?

Industrial = 92% pure, Food Grade = 95% pure, Medical = 99% pure.

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.
