Boyu in-line diffuser help

[AdAndrews]

Hi guys, ive been listening to my boyu diffuser- sad i know

anyways, what does yours sound like, sometimes, mine sounds like in-consistent, like one second bubbles are coming through faster, the next slower, and then repeated, like up down up down.

is it broken?

On a 180l tank mine was consistent after about a minute. Its possible that what you hear is the gas being restricted as the non-return valve closes and opens again.

Sometimes my bubbles from my bubble counter are not uniform but the stream of them over say 10 seconds gives a steady pace.
I think its something to do with my check valve.
