I have only anecdotal information, but I have a 5lb tank supplying CO2
to a 75 gallon tank. I have it set at about 2 bubbles every 3
seconds. I feed the bubbles into the return pump of a trickle filter
so I'm pretty sure the bubbles are completely dissolved and I'm not
wasting any CO2. This tank has been in continuous operation for 3
months and it still feels as heavy as when first refilled. (I know not
scientific.) So I expect it to last quite a while longer.
As for refilling the wisdom in the archives says that most welding
shops won't fill 5 lb tanks. I got mine filled at a commercial fire
extinguisher company. It costs $7 to fill.
Hope you have a very nice day, :-)
