The pH change didn't kill fish -- something else did.  My fish undergo a pH
swing of 1 or more units over a period of 5 minutes once a week with a water
change.  Even fish that are supposed to be sensitive to pH swings tolerate
it fine.  My pH meter is on a timer as well, and I see pH swings of .5 units
every night.
