Would This Regulator Be Okay?

My dad just found an old regulator he had for his saltwater aquarium and i was wondering if it would work for my planted tank. Kind of tired of gdoing the 2liter bottle thing

If it is made for co2 (for calcium reactors i think) then it should be okay Just look for the right tank that will fit the regulator, check if it still works also.

The brand looks like eheim.

Just look for the right co2 cylinder i think.
