C02 Diffusion

slim20012 · Oct 28, 2007

Is it possible to diffuse co2 through a normal airstone it would be a home setup one like nutrafin sorta ?

You could be you would be wasting alot of co2. airstone bubbles are too big, and will jus pop when it reaches the surface

slim20012 · Oct 29, 2007

was just thinking because their not under the pressure a pump would make that the bubbles would not be as big

They would be more lilkley to be bigger with out a pump beasue the pressure of the pumps would force them out of more the holes. Lower pressure would only allow the C02 to gather and escape as larger bubbles through one or more holes.

Just my take on it mind.

Guy at LFS told me yesterday that you have to use an airstone with DIY CO2 as the pressure is not enough to push the bubbles through a glass diffuser. I think some members of this forum might disagree.

I just bought one yesterday! :hyper:

It seemed like a good deal but have to wait till it arrives to test it. Its locate in thailand so its going to take forever to come. :angry:

On another note I have heard of people using lime airstones with good results. :good:

That's good to hear. I've got a nano glass diffuser on the way and DIY set up under construction.

Always take the advice of the forum over the LFS! :good:
