What would anyone recommend for bubbles per minute into a 20H? I have a DIY co2 setup made out of a paintball tank and a glass diffuser, I can tune the stream of bubbles but sometimes the drop checker indicates that too much co2 is dissolved in the water. How can I keep an equilibrium between co2 constantly running and a medium co2 ppm that isnt harmful to my inhabitants?

The bubble count is unique to each setup. You will need to fine tune your BPM to your system. It sounds like you might need to turn down your flow just a tiny bit.

start at 1 bpS and work up from there. No one can tell what to run it at. Adjust over the course of a few weeks.
