:!: new subject, my difuser, I have the spirel type, But i have an anoying build up of co2 wich realeases ever 2 mins or so from the top chamber. I have added 16 chamber now in hope that it would stop due to difuseion, But not matter how many i have it just dont stop. Any help please as i think its anoying and proberly is a waste of co2!
You have editted the original thread - the original thread you posted was regarding gauge pressure - this is totally different now - trying to make me stupid.
This build up of gas at the top of the spiral diffusion is not pure Co2, Co2 gas enters the bottom of the spiral diffuser as one large bubble, as the bubble travels up the spiral it should get smaller and smaller until its get to the size of a pin head or slightly bigger. At the same time, other gases which are naturally dissolved in the aquarium water penetrate into the CO2 bubbles. These so-called waste gases explain why the bubbles do not dissolve completely, these waste gases are what is collecting at the top of the spiral diffuser which vents its self every 2 minutes as per your thread.
Are you big bubbles at the bottom and small bubbles at the top - if you are this is working correctly
have a look at the attached video
or JBL video, after 3.30 mins its show you about the spiral diffuser - sorry its in German
Hope this helps
