•I CHECKED THE PH OF EVERY SAMPLE DAILY.
	•I ADJUSTED THE PH BACK TO 4 OR 8 (DEPENDING ON THE SPECIMEN).
	•THE PH JUMPED APPROXIMATELY TO PH 8 EVERY DAY, WHICH WAS NOT EXPECTED.
	•FROM A PREVIOUS STUDY, MONTENY ET. AL, THE PH DROPPED FROM 7 TO 1 IN 10 DAYS.
	•I EXPECTED THE PH TO DROP MORE EVENTUALLY, BUT THEY DIDN’T.
	•THIS IS AN EXAMPLE OF ONLY ONE CYCLE.  SOME CYCLES SHOWED DROPS IN PH FOR INITIAL PH OF 8 WITHOUT ADJUSTMENTS.
