Hi I have just installed a ceramic diffuser in my 100 litre tank and the cO2 bubbles come out in a few, 3 or 4, very thin streams, not really a mist but the bubbles are pretty "micro". The bubbles rise sedately upwards and are then sent off round the tank by the output of my in-tank filter. They don't make it to the surface too much, any that are still visible end up caught up in the plants. So that all seems fine. (Correct me if that's not good.. )
Only thing is the diffuser is making a faint squeaking noise all the time, I guess as the bubbles force their way through the pores in the disc. I can't think how but is there anyway of shutting it up? Or is it down to quality of the diffuser? Anyone else have this problem? I soaked the disc before installing it, which I did read somewhere was a good thing to do - although I wasn't convinced at the time.
Any help gratefully received!
