dipping my toes with CO2 couple questions about CO2 monitor

I plan to run CO2 next run , now will this even work lol I have 35x15x8 grow room. I'm going to get two co2 tanks and hook them up to fans located in different areas of the grow room. now here the dumb question I was given a CO2 monitor which has a plug in for the co2 regulator. can I buy a Y split plug the two regulators and then plug that into the controller. basically turning both tanks on and off when the target is met. thanks lol. I'd like to try a run of this before going full out and getting a burner.
