Should I Add A Bottle To Prevent Overspill?

[geo7x]

Ive just got a nutrafin co2 kit and was wondering whether to add a bottle along the airline tubing (sealed of course) so that iff the mixture somehow gets sucked up the tubing then it goes into the bottle and not the tank ?
Is it worth doing?

Heres a diagram of what i mean:

You could if you want and be on the safe side, I do with diy Co2, but if you do the mixture right it shouldnt overflow into the tank.
