My API test kit is 2+ years old, it seems to still be working well.
Ammonia in this tank is .25 to .50. I did two water changes, one was the first fill up after adding the pellets and plants, then another because I set the tank down on a cable. I had to take off one filter because I need a new impeller part. It's been 4 days since the tank was set up, overstocked with fish, for sure. Last two days, filter, heater, lights have been out because of the snowstorm.
Thinking that's not too bad for the ammonia score with all things considered. What do you guys think?
