just curious

How long does a 10lb co2 tank last everyone?

[mark]

think was about 9 months

I just replaced my first 10lbs the other day....about 14 months. It will be half that time for the next one.

At the height of my coral growth last year I was lucky to get 5 months out of a 10lb bottle.
Right now i figure I'm using about half of what i was but my cal demand has been steadily increasing over the last 2 months and i expect it won't be long before i'm back to what it was

As Marie points out, it depends on consumption. I used to get anywhere from 4 to 6 months out of mine on my old tank. My new tank has very little consumption, so I expect closer to a year until things start really taking off.

for most people what is your bubble rate?

[untamed]

As the controller doses the CO2 based on pH...the bubble rate in my system doesn't matter. When the controller calls for CO2, I think it bubbles at about 2-3 per second.

I used to get about 10 months out of my cylinder when I had an Ocean Aquatics skimmer. Then I switched to a Schuran Pico and the consumption has gone up (which I find interesting as its supposed to be a recirculating model and scavenges co2). Anyway I can go anywhere from 4 months to 8 months on this one.
