I am looking into a c02 system and was wondering how long a one liter bottle would last. Its for my 29 gallon medium light. So I'm guessing about 1-2 bps.
I would at least do two 2 liter bottles, switching out one every week. You want one 2 liter bottle of co2 for every 10-15 gallons.

That is the recommendation for doing diy CO2.
Are you doing DIY or pressurized CO2?
