The brew I'm making at the moment frothed up 18" above the CT surface yeste=
rday after 24 hours of brewing but today there is just a few inches of foam=
. Where the old foam has stuck to the side of the tank it is quite smelly. =
Would this stuff be the same as biofilm and therefore would be detrimental =
to the CT?

I took out the compost and continued the aeration (6ppm O2) until I apply i=
t tonight. Being curious, I added 2 tablespoons of malt to 100 gallons of C=
T and watched the O2 drop to 3ppm in 12 minutes. Amazing! I don't know how =
long it took to get back up to 6ppm.

If you're reading this Elaine, I hope you have an interesting week at your =
Coff's Harbour seminars and you have plenty of newcomers to educate. It wou=
ld be good if there were fellows from the Department of Primary Industries =
present, also garden magazine writers, and garden TV presenters.

Scott
