How to determine how many bubbles per second?

Hello! Im a younger hobbyist just getting into CO2 and don't know much. I had a friend set me up with everything I need to start my system. I currently have a 15 pound cylinder and am very confused on how to determine how many bubbles per second I should use. Is there a specific ratio bubbles per to sec to gallons? I don't know if it'll help, but I'll include that I have a nano 125 gallon with plants that are thriving but very slowly. Thank you!

Nano is not 125 gallons, that is a large planted tank, no where near a nano planted tank

bubbles per second will not serve you well in a 125 gallon, you'll likely need to buy a flow meter that measures cc's of gas.

@Greggz is a fairly active promoter of flow meters and has a tank of similar size, he should be able to weigh in a decent starting point for cc's.

There are quite a few here now using a flow meter for large tanks. I've been using one for several years and couldn't be happier with it. With the flow required for a large tank, it's impossible to count bubbles, and a flow meter just seems like a more elegant solution.

Here's a link to a point in my journal where we discussed it again recently.

And here's a link to another recent thread.

Hope that helps. And this all assumes you really do have a 125G tank, and not a nano 12g or something.
