Yes, the tank this was pulled from has Co2. You are right, I didnt want to treat the whole tank with the possibility of melting down all the Mini Rose, so these are specimen containers(deli cups). Im not sure how much impact that will have versus a tanks conditions.
EDIT: In a tank I should still be dosing the ferts at regular dose right?
