Here's the deal,

Lets say I want to make 5 gallons CT.

1. I have a 6" Diameter PVC pipe long enough to hold all.
2. I have a 36" Diameter tub that'll hold everything.

I have the bottom covered with one flat disc air stone.

Wouldn't the air needs per minute be different to create identical oxygen concentrations? Know what I mean?

Are you stating that the shape of the container or manner in which the oxygen is dispersed is going to effect the dissolved oxygen levels in the water?

I'm not sure I understand exactly what equipment you have an how you're putting it together...

What I'm trying to learn is basically the effect of air bubbles dispersing oxygen within the water. In a long tube the air bubble released at the bottom will travel through more water, so...will it be releasing oxygen it's entire trip?

If it does (not affected by pressure or something) then a few bubbles can do the work of many bubbles (that would be spread out in a larger sized bottom but not as deep water)

Or to say it in "Cheapest way to design an ACT brewer" (same volume of tea) my air pump could be a single, simple air stone if placed at the bottom of a tube where its bubbles would be more than adequate to provide oxygen because they travel through the water for a longer period of time!

There's other factors to consider I'm sure but my mind happen to visualize the above concept.

Back when i used to work with aquariums alot surface area mattered also. When the air bubbles break the surface tension of the water it helps to oxygenate the water. in that case the 36" would be better.

Which one is easier to clean? 100% clean is very important.

Make sure you don't have any dead spots that aren't getting air in your design. Air stones can be problematic to clean, which is very important.

I would design your brewer to work in a round 5 gal. bucket for convenience purposes.
