[APD] How long does your CO2 last ?

[Phillip Grobler <pfgrobler at gmail_com>]

Hi,

Could any one give me a rough idea as to how much CO2 they are using.

How long should a 2kg bottle last on a 100g tank, with little surface
movement, canister filter, closed canopy and  moderate to high
lighting ?

I'm  need to decide between a 2KG and a 5 kg bottle, but the 5 kg
bottle will not fit upright
under my tank So I'd prefer the 2kg if it will at least last a decent
amount of time.
