I have been using ceramic/glass diffusers for years to inject CO2
into planted tanks. They always have a tendency to make a little bit of noise, but generally not so much that you notice it unless you are right next to it and listening for it.
I setup a tank recently, and the diffuser is making an awful whistling noise. You can hear it from the other room it is so loud. I have tried adjusting the flow of the CO2
a bit, but can't adjust it too much one way or the other if I want to inject CO2
at the level I want in the tank. Anyone come across this before or have any idea on a fix? It is driving me nuts.
I attached a couple of pictures - 1 is of the diffuser in question, if that matters. The second shows the system. It is an ADA 74-YA Ver2 with an ADA El Valve solenoid. I don't think it has anything to do with the system itself. The noise is eminating from the diffuser itself as far as I can tell. And, I have used the system before with no awful noise.
