Thanks for the reply Bob.
I don't enjoy develpoing a brewer. I'm a
small market farmer and started making this brewer for myself when the only
small brewers on the market were the soil soup and the GSI, before the KIS, your
brewer and others were available. I figure since I've got money invested
in some equipment (tank, air pumps, hoses and diffusers) I should try to make it
work.
Your brewer has been described as having larger
bubbles. Do you have any idea how the bubbles coming out of 1/4" hose
would compare to your bubble size?
Would it be possible to use my tank and air pumps
with your air diffusion set-up?
thanks,
daniel

A few days ago my message was that some enjoy developing a bewer, some like
to work at gardening. Developing and testing a
brewer is a several years challenge.
2 CFM for 20 gallons? The Bob-o-lator uses less than 1 cfm for 250
gallons and maintains very safe D O2 .

This is intersting info. I'm working on a
brewer that I started making last year. The container is 12" round by
4' high (it holds about 20 gallons) and uses 5 tetra tech deep water pumps
which gives me a total of 2 cfms without any diffusers attached. The
air hoses are 1/4 inch diameter. I think it would simplify my design
to not have to use air diffusers and just let the air come out of the
hoses.
Anyone ideas if this would provide enough air
without diffusers.
thanks,

Wow, that
seems to be "new" info--I seem to remember lots of discussion of size of
bubble vs. surface area, but this statement explains the larger
bubble size in the Kis Machine and the Bob-0-Lator.
Will you elaborate a bit when you get a chance. What is too
small? I know the bubbles from an aquarium stone make tested adequate tea.
What about diffuser bubbles? Too small? Or is the real answer: get a
O meter and make sure you are 6 mg O2 per L or
better?
thanks,
jeff
