Jeff -- I think you're being harsh on TaChung Huang, and not recognizing he
is testing. I take Huang to translate as John in English, anyway, a boy's
name? TaChung, are you a boy or a girl? Do you prefer TaChung or Huang?
I'm dumb in Chinese, with a difficult American boy name, too.

<<<<BTW: I have been using the practice of splitting the "food" 8 hours
apart; adding half the food in the beginning of the first 8 hours and
then adding the remaining one quarter of the "food" in two more food
additions. This practice have reduced the DO plunge in 12th to 18th
hours into the brewing cycle. Does this make sense? >>>><

Testing is what tells you what makes sense.

Clearly, Huang is doing real time testing and has some handle on it. Paul
Sachs does a similar thing and I think both of them are onto a potentially
best practice.

And I, for one, still believe real time testing is the most important
testing we can do. Where are those real time tests? I'd bet most folks
here can't justify or afford or access SFI tests and to be blunt, not quite
yelling, I think it's more appropriate for those who are making money
providing tea or machines or composts, not every user, so I'd appreciate
less harping... Everyone shouldn't have to do a $100 bill to speak up,
especially when they're clearly paying attention. Much praise and thanks to
those who can and share here.

> Bob: Thanks for posting your testing results.
Your numbers actually reveal some consistency that the air pump to your
first brewer is not "identical" to the other two. The DO of the first brewer
is consistently lower, in test 1 and 3, when fish was used. Fish has more N
then Kelp does, I suppose. The third brewer was also producing less air then
the second one and it became evident when the fish was used. <

Huang -- How did you reach these pump conclusions?

PS -- I screwed up in a prior post (Hey, first time!) saying larger tests
at my favorite lab were separated protozoa and ciliates, which are among
protozoa.
Duh. Meant to say protozoa and nematodes, in case I caused any confusion...
