you will care when you are in the middle of a game and it messed up.. becides you can get your anti-syphon added to your tank for a few dollars...or buy a new tank with it already for a few dollars more than a normal tank...read your owners manual..if it says not to use a co2 tank then they dont have to waranty it...

OK I admit defeat I over read at the bottom it say "Use only Co2 with anti syphon for best results." I ordered a N2 the other day, and getting it tommorow I just wasn't sure to keep it or not.
