API test kit readings question
I have the API Master test kit which I have had for over a couple years. It still shows its good until 2015. I am wondering if maybe it has expired prematurely. The ammonia test gives consistent readings, however it is telling me that my Amm is sky high between 3-4 ppm. I have conducted 3x 75% water changes over the course of a week which got it down to 1-2ppm. However now its back up. Heres the thing there are no fish in here! The last one died of old age recently. It was quickly removed.
Is there a test solution I can make from the store bought Amm I bought years ago to fishless cycle the tank, to make sure my test kit is still accurate?
I know when I test tap water its zero.
One thing that could have happened is when I first discovered I had sky high ammonia I dosed a very small bottle of stability that was opened and had been sitting on a shelf but not expired. When that did not work I bought a bottle of tetra safe start. I then learned that if you dose these products when the Amm is already 3-4ppm it is deadly to the beneficial bacteria as well and that dechlor products will render it innefective. So I did one more 75% water change to get it back down to 1-2 range. Then waited 24 hrs and dosed one more small bottle of tetra safe start. After 24 hrs its sky high again. I am so confused by this that I almost think the test kit might just be way off.
