AC110 MODIFICATION Idea???

Oh, and too much air could adversely affect the bio-mass by drying it out in part.

false; fake; in error.

for agitation...in stagnant water, the surface will reach saturation quickly but the water below must rely on diffusion. With an air stone, power head, or any filter the water gets mixed up through the agitation. Any mechanical means that will bring the lower water to the surface and cause the surface water to be carried below will increase the gas exchange within the body of water as a whole. An air stone increases the surface area by adding the surface of the bubbles into the sum total with that at the actual surface. However, there is a missunderstanding that just causing the surface to jiggle (agitation) or to create waves (also agitation) that this will do miraculous stuff like remove chlorine from the water. The word 'agitation' is really too general and it can cause a lot of missunderstanding.

But for AC filters, I am no expert. I have a small one so I can only say that in the smaller ones, an airstone would hinder the flow because the sponge is not designed to flow air and water at the same time. The air bubbles would get trapped in the sponge, partially clogging it.

Yes...it is a part of an arguement that is faulty in logic.


The ripples at the surface do expose more of the water to the boundry between liquid and gas where the major exchange takes place.Also it will disrupt the film that builds on the surface that you can see in still water.
As you said the lower water will surface by being drawn up along with the air this was understood. Wasn`t aware or didn`t see that the bubbles also have surface area(DOHH) You can`t gas off chlorine... excess CO2 is a different story...

Thanks all! Fun stuff here... good discussion. Seems a day doesn`t go by for me at MFK that something isn`t learned http://www.bioconlabs.com/oxy.html

You can off-gass chlorine...you cannot off-gas chloramine.

'Off-gassing' beening the generalized term for gas exchange here... So to speak .

Chloramine...


Was watching the waterfall from the AC110 as I did a 40g WC on the 125. The largest bubbles just rise and the ones on the periphery, will call them microbubbles, don`t even seem to make it to the surface. So much for the understanding of airstones from UG filters
