I,m a newbie....are airstones used in tanks with a CO2 systems? Will the bubbles from an airstone not cause the CO2 to escape to fast and not benefit the plants?

it depends :P

what kind of co2 are you using? DIY or pressurized?

the bubbles will cause the co2 levels to go down, but if you're using pressurized, you can just up your co2 usage. some people only turn on the bubbles at night; i personally just don't use bubbles when i'm using co2 (diy).
