Random question about bubbles per minute

[tim_s]

Just curious if I am on the extreme side with 60 bubbles per minute. What are your bubble counts?

I ran everything from 1.5 bps to 7 bps on a 40. It's very dependent on the diffusion method and surface agitation, but also light level.

I have not seen a drop in pH yet! I have increased my bpm to roughly 2 bpm.
