Anthony:
Thank you for doing the work and posting this chart. However, I don't have=
enough information about this chart to make heads or tails of it. Could y=
ou provide an explanation? Without one, I am hoplessly lost. I'm sure it g=
ives knowledgable people a lot of information but I am at a loss except for=
the fact that a change of some degree took place within a general time spa=
n.
For example, it seems like you have a drop in DO within the same range for =
all tests then a return to higher levels. What did you do (or nothing) to =
cause the change? What caused the return to higher levels? Was the air co=
nstant? Was it exactly the same compost in the same amounts? How much wat=
er? How long was the brew cycle? What was the temp of each test? Did you=
use dechlorinated water or well water or ??? Did any part of what you did=
change from test to test that you may have thought inconsequential? For e=
xample: Did you add your inputs in the same order each and every time or d=
id you add them all at once then put in the compost or did you put the comp=
ost in first then add the nutrients? Did you aerate the water before putti=
ng in inputs and was it the same each time? Did you put in the compost firs=
t or after you had let the inputs dilute in the brewer water? What kind of=
DO meter? Did you calibrate it after each test or use the same calibratio=
n for all tests? I say this because mine has to be calibrated quite often =
or the results are unreliable. What was the time for each test and/or did =
you brew at exactly the same time each day? I say this because it seems th=
ere is a correlation between tides and cellular growth. Even if you do the=
same things on subsequent days and each thing takes three days, you are fi=
fteen days apart from the first thing to the last and this can skew results=
enough to account for the differences shown in the graphs. Of course, if =
you brewed them all at the same time the changes would be less significant.=
I am also a little confused by the timing on the bottom. Do you mean tha=
t each mark is 5 min so that a reading at 8 is actually 40 min.?
Thank you,

Subject: [compost_tea] same recipe
Just to lighten things up a little bit! :)
Attached are some plots of the same recipe DO curves.
Now what happened to the yellow one and is there anything wrong with that=
is drops a bit for a bit?
And what about some differentials on the rate of change of the bacterial =
bloomage sections, seeing that we are back to school :)
