Throw out all your API test kits!!!

I would strongly recommend reading the write up that Jason2459 did on various test kits, lots of testing and documentation. I personally use he Red Sea test kit for ammonia always been pretty straight forward and easy to use. The yellow is zero, light green .25 and so on, easy to compare even for the color blind person like me.

I have switched to Red Sea on all of my kits now and am very happy with the results on all. the Phosphate Pro at 0.02 accuracy is really great,although a little difficult to read.

I dont think so. It was API fresh on freshwater. He was just chiming in on API as a whole.

Correct, was just a general warning about the API freshwater ammonia test. I believe the saltwater test is the same reagents but slightly different color card (my new set has both color cards).

Anyway, I received the replacement test set they sent me and it's working as expected. I did a side by side of my old set and the new with tank water and deliberately ammoniated water...very clear difference in attached image.

The symptom of the kit going bad that I had failed to notice was the contents of reagent bottle #1 undergoing a gradual color change from clear to amber.

All 3 with the exception of the blue one, all look the same color to me.
