hi joe
iuse the test and it still gives me hadeake .
at list half of the times are not as it should be
im at the begining of the way and it give me direction.
i just put abigger pump and it already looking better
i alsow parchesed a PH tester and i start to take test from old BD sampels (unwashed)resault 12.2-13.3 how doese that sound?
tested as well somewvo i got 8.4-8.5 i thought it should be acid? have u got any idea
all the best

Hi Joe,
I use every test on JtF to test my Bio and also the the Hanna
Instruments test for Glycol. I do this every single batch. I have never
had any fallout in Jans test to date.(Knock Knock Knock on wood) ( I
measure it out precisely ) I have graduated to the base/base method and
have had absolutely great results. That said I got into a washing awhile
back that was not as good as I like so I investigated and found that I
am dealing with FFA's that are higher than I want. I am moving to the
acid/base learning phase for that. I did also learn that if I pour the
WVO that is liquid and on top at 28 deg F into a bucket and process the
stuff that gets clumpy (on bottom) I greatly reduce the FFA's in the
oil. (14% or so lower) compairitably (tests of each done side by side
same temp same everything except oil and very precise). So in the
future winter freeze cycles I will cut out the dark top stuff and save
for Acid processing. I have since adopted this and my bio stands up to
intense stir washing each and every wash now.( I get clean and clear at
the third wash but I do go 4 just because) I might add that after I
take a grab sample from the batch and mix 50% water, then give it a 30
second shake, it separates into 2 phases in 1 minute or so.(thats at 50
- 60 deg F water) That is my first clue I have a good thing going.
Hope this helps.
