Mike, it's quite important for you (and your fish) that you know the concentration of CO2 in your tank. To do this, you must have a means of measuring pH and KH (carbonate hardness). With these two measurements and the use of a chart http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm you can read off the CO2 concentration in your tank. You should be looking for 10-25ppm. The amount you need to bubble in depends on your filtration system and the amount of surface agitation you have, plus of course how much the plants are using.
I would guess with a 35 gall tank, 1 bubble every 2 seconds would be a reasonable place to start, but do the measurements first.
