Hey all. I thought I would update you on what I think was the culprit in the debacle that occured in my tank about a month ago. I had tested my water the other day and filled one to many vials with water for testing. I tested my PH and the test color was yellow indicating a PH of roughly 7.4! I must admit I was a little confused how it could happen for a second then I figured I would test the unused vial that I had pulled at the same time. This time I shook the PH test solution bottle. The test came out a nice purple indicating 8.2-8.3 as it was supposed to. Looking back I think I added buffer as a result of a bad test. I took a picture of the two vials.
