Here is a good video on how to setup and use a pressurized CO2 setup.

I have a similar on my 95 gallon planted tank. The key is to adjust the bubble count appropriately to not over-dose the tank. I use 3 bubbles per second. I started with 2 and gradually went up. You will have to just watch your fish and see how they react.
