Ha. Ha. Ha.
I live alone, so unless my cat did something, then the mystery continues.
No, I did not test wrong. I use the API liquid test... I tested it with the normal ph test and it immediately went high, then with the high ph test and it immediately went high.
After refilling, the ph is at 7.
Factors: The water was not dechlorinated, it was simply a test fill to see if the tank held water. It has new sand, and an old piece of driftwood that was rinsed in hot water before being put in the tank. It sat overnight.
