[compost_tea] Re: pH



Laura and all-

I also "brushed off" the pH meter, hadn't bothered in a long time!

Finished AACT 6.4
450 ml fish hydr and 150 ml. liquid kelp in a kitchen bucket of water 
3.4
Add 3 spoons of baking soda to fish/kelp soln 5.8
Add pH adjusted fish/kelp/water to 80 liters AACT 5.9

Done this way, the baking soda didn't touch the organisms in the CT, 
just made the added microbial foods more friendly to them when dumped 
in the spray tank.  There would be a certain amount of Na+ in that 
"fish water", would prefer not to have that but hoping the amount of 
"salt" in nearly 90 liters of liquid is less problem for my 
bacteria/fungi than a pH under 4...no?
