I have been using 600 g disposable CO2 cylinders to provide CO2 gas to the Fireplace Aquarium and that has been pretty good. One cylinder lasts two or three months and they are a reasonably unobtrusive size. Recently though I have been going big. Welder’s Warehouse has a two extra-large cylinders combo deal. Each cylinder holds 1300 g of CO2. Surprisingly, the larger cylinders are not much taller than the 600 g cylinders I have been using so they don’t take up massively more space. The other nice feature is they come with a flat bottomed plastic collar base and stand stably upright on their own. The smaller cylinders just have the round bottom and so need to lean up against something which is always a bit of a worry.
