Hold on a minute my test kit may be expired! >:| looking at the ammonia and nitrate bottles, it says 0806 The nitrite bottle says 1008. The pH says 1008. I believe the pH and nitrite is accurate. I read the API test kit is good for 3-4 years. And if the nitrate and ammonia were made in 2006 The results are off. I googled how to find out if it was expired it said the last four numbers is the month and year. Any way I can yell at API, or petco for not taking it off the shelf? I bought this in what, February? What do you guys think?
