My PH and carbonate levels have dropped significantly so I retested with my regular test strips which showed a normal range. I then tested with my API test kit that matched my regular test strips. I then took a sample to my LFS which also agreed with my results. I tested 3 more times with these strips and all 3 showed that my PH and carbs had dropped significantly. I do not recommend that overdosing can be very dangerous, especially at the level these strips showed. I bought these for convenience and they were a lot cheaper than my regular strips but not worth the risk.
