The one from Green leaf aquariums requires a minimum pressure of 30 PSI so, yeast CO2 will not work with that. Using another bottle is a good idea. Put a fresh batch in it halfway through the life of the first bottle then, replenish the first bottle through half the life of the second bottle and repeat. You might get a more consistant CO2 supply that way. you can put a check valve right after each bottle then run them both to a T connector, then to your diffuser. That way you can remove 1 bottle without losing the CO2 pressure in the line to the other bottle.
