Yes. For the ammonia, nitrite, and nitrate tests they have to sit five minutes if I remember right. There are instructions on the back of the little color cards for each test.
The color gets darker as you let it sit, so your ammonia is probably higher than you think.
Yep, that is what the test calls for. Wait 5 minutes MINIMUM for the nitrate test to color up.
My API kit just passed the 1 year mark, I probably will not replace it with API, might have to go Salifert instead.
And as others said, always shake the bottle a bit, even when the test does not say to. Shake the crap out of that nitrate #2 bottle.
Others here have reported the "false positive" that I get with the ammonia every so often. You can run the test 10 times and 3 of them will read .25.
I've had it with the pH test. I've kept a solid (no doubt about the color on the card) 8.4 for the longest. Yesterday for the first time in forever, I got a 8.2-8.4 maybe sorta can't really tell.
I'm done with that uncertainty.
