I have just started brewing my own AACT here in New Zealand, we had
the last two brews tested at SFI(New Zealand), the total bacterial
biomass came back very high, but the active bacteria biomass came
back low, if anyone can help me better understand why the active is
low while the total is high, it will be much appreciated!
Here are the figures.

Sample 1
Bacteria
Active-27.6
Total-1041
Fungi
Active-5.05
Total-19.83
Diameter-2.5

Food- 0.17% blackstrap mollases
      300ml humic acid
      1 pound of seaweed powder
      24 hour brew cycle 1300 litre brew
      lowest temp 16.5 celcius



Sample 2
Bacteria
Active-0.3
Total-1009
Fungi
Active-2.38
Total-8.13
Diameter-3.3

Food- 1.35% blackstrap mollases
      750ml humic acid
      5 pounds of seaweed powder
      24 hour brew cycle 1300 litre brew
      lowest temp 18 celcius, out side temp 5 celcius
Sample two would go into the minus on the oxygen meter within minutes
of taking a sample out of the brewer, so there had to be a lot of
activity happening i would of thought, (sample 1 took 20 minutes),
both samples were tested 7 to 8 hours after the brewing had stopped.
Are the bacteria going to sleep befor we test them?
If there is a high total bacteria biomass were they all once active
in the tea at some stage through the brew cycle?

Thanks Russell
