8:30 P.m. - Lights reverse off as I'm preparing to test central bath-water parameters. Pulled a still water test from front of tank and tested pH, ammonia, nitrite, nitrate. pH color chart suggested ~6.4, which is the lowest reading I've had since tank startup (~45 days ago). Ammonia, nitrite, and nitrate levels sat'; planned to do weekly the highest swop following day. 8:40 p.m. - Turned lights back on. Added powerhead to tank; placed on left, straight away below cannister vent; powerhead shop about two inches above gravel, peaked at front left-wing corner, askew with cannister shop move. Observed bath-water stirring via ingrain leaves, fish, and stirred detritus. Found swifter, sat' sign along radius of front plate glass to vis-/intake/exact side of tank. Found slower, sat' action in center of tank. I'm puzzled by the hasty mutation of pH. It seems counterintuitive. If C02 lowers pH, and integument arousal adds C02 as well as Oxygen, then the pH should have been stabilized during the three hours the bubbler was...
