I am not too familiar with that light so I cannot tell you in certain terms what kind of lighting you have. Perhaps other members here can chime in.
However, if you cannot afford pressurized CO2, then DIY CO2 is another method you can go with.
It is possible to maintain an aquarium with no CO2, but these are generally lower light aquariums; in medium light and up, CO2 is generally needed in order to keep the plants healthy so that algae does not take advantage.
