I have a 65 gal glass tank, I use a whisper filter and a dual line air pump I dont seem to be having any trouble with fish they are breeding like crazy. but I see that some are adding co2 into the mix why? what is the benefit? dont fish being live organisms give off co2 as a by product of respiration? I want to do the best I can with my tank

People add CO2 to their tanks for the benefit of their plants, if you don't have any live plants in your tank, then you need not worry about the CO2.

mick as marie stated Co2 is used in planted tanks to enhance growth ..it is nothing to play around with unless you are very familiar with it's effects on your fish and water chemistry..

Mick, it's not really necessary in a tank without heavy live plant growth. Plants when photosynthesizing during the day do the opposite of animals--they give off O2 and take in CO2 (and vice versa at night), and only in a truly serious planted tank would you ever have to worry about the plants outstripping the CO2 in the tank.

Jeff is right, you should be aware of the effects first before you start adding it. It usually has the effect of softening the water because CO2 converts in between many forms, including carbonic acid when it is dissolved. If your fish are breeding and all is well, why mess with a good thing...
