Foaming Bountea

Time for another dose of Bountea in the garden.  I left it a little long and the foam started spilling over. 

I believe foam is a great indicator of biological activity and am told it contains the bodies of dead microbes!

I have heard that some "experts" say the foam comes from the yucca in the Bioactivator.  This does not quite make sense as it only happens when it is warm and has been brewing for a few hours.

If you want to reduce foaming, just add a little cooking oil to the brew.
