Alright....
Someone needs to tell me what's going on here because I'm stumped now...
After fearing that my API Freshwater Test Kit was expired (I've had it for about a decade, maybe less), I ran out today and picked up separate API tests for Ammonia and Nitrate (they didn't have the complete master kit in stock) at a local Petco. When I just ran the numbers, the results were the SAME as what I get from my old supposedly expired kit, which were:
Ammonia: Between 0 and 0.25 (the fluid is pretty much yellow in color)
Nitrate: Between 0 and 5.0, but closer to 0
I don't understand this...I'm on my fourth or fifth consecutive water test and the results haven't changed. I'm SURE I'm following the directions for each test to the letter.
