What is correct bubble count for 15g planted tank

[Bsurfr]

I have a new co2 system and am wondering about how many bubbles per minute I should set it at. I have fish and shrimp im my tank too. Thanks

There is no magic number. You need a drop checker and 4dkh solution. You then adjust the CO2 flow to hold a green color in the drop checker fluid.

By my own personal experience, Im starting to trust drop counters less and less. You should probably have one, but you should bring your co2 up slowly until you stop seeing problems or your fish start being affected. And by slowly I mean over days, not hours.
