I'm taking the plunge into pressurized CO2 (finally) and have a 46g tank with 96 watts of light. I have no idea whether to get a 5lb or a 10lb CO2 tank though. I have room for either. Given my tank size and lighting, which would you get?

i say bigger is better! it really comes down to size and price if your not concerned about either then go for the big one. i prefer to have the biggest tank i can get and hide!

P.s. dont forget to chain your tank when you get it!

I'd go with 10. My gas shop has two different forms of 10 gallon cylinders. The other reason is that the gas shop has a ton of 10 gallon cylinders so there is never a problem getting a tank swap.

Get the biggest one you can, it wont go bad. Longer between refills is good!

The cost of the gas doesn't really change much, from 5 to 10 or even 20 (at least at my local shop). It's something like $10 to fill a 5lb and $14 to fill a 20lb. I'd opt for the biggest that will fit.
