How Often To Fill My Co2

[Boyden]

How often should I fill my CO2 dispersion unit?  I only just bought it and I really would like to know how often I should use it for a 54 litre tank.
 
Thanks

Are you talking about Pressurized Co2? if so what size is you Co2 canister? and how long is the Co2 on each day? and how many BPS (bubbles per second) is the Co2 running at?

I assume you mean the fluval ones that hold the Co2  and allows it to dissolve into the water column?
If so, refill it at the most twice a day, but once is fine =)

Thanks very much  Someone told me once every three weeks.......... I shall be filling it at least once a day then
 
Thanks again.  It's always nice to be certain.
