I was hoping to run a search and find someone that may have experienced the same thing. I had no such luck. I just purchased the Salifert test kit after getting some strange results with SeaChem. Problem is, the Salifert readings don't match anything on the color chart. Not even close. I am getting a brownish grey color. I even ran the test against a known 8.3 sample. Ironically, it is the same color I was getting with my aquarium water but still doesn't match any chart color. I couldnt' even consider it between colors. BTW, Seachem and Tetra both return 8.3 results. Did I just get a bunk kit?
