Question about API liquid water test.

When i test for ammonia it reads .50 ppm(green). I left it covered in tube over night and next day it read 0ppm(yellow). Which is right? Umm, i may have not followed instructions completely.

Sounds weird, did you leave it over night on purpose?

In my experience the API tests mature the longer you leave them, or develop even. But I haven't left them over night before so who knows??

If your reading .50ppm and its definitely green then I would take it that there is some ammonia present, I wouldn't leave it any longer than 5-10mins max. after 5 mins you will have a pretty accurate reading.

Peace always..

If you worry you die, and if you don't worry you still die..... so why worry?

Are you picking up any other params? like nitrite etc?

7weeks, should be nearly there no? any fish in? and or live plants? sticking a good few fast growers in there will help suck up that small amount of ammonia.

Has there been a spike of ammonia? like up around 3-4ppm? and then on its way back down again?

Peace always..

That's really weird. I have left test solutions in their tubes overnight, and none of my tests get a different reading after the initial 5 minute wait.

Ok. Heres where I am. 7 weeks in, 20g, 2 platys, 2 anubias. Change water 50% every other day. I would've thought it would have cycled. gh-11dh, kh-3 dh, ph-7.5, ammonia-.25 ppm, nitrite-0, nitrate-0 or very close to 0, according to color chart. Is that way off or do i need to wait?

Definitely let the solution stand for 5 minutes before doing the reading AMD doing the reading upon natural light helps a lot. I've been told to reduce water changes though now my ammonium is spiking and I can't get it under control. 0.25 though is not bad but nor is it ideal I've been told. Trying to get it to 0 is ideal with other readings.

Ive had the ammonia spikes. Aggressive water changes will get you through it. Thanks for the natural light tip.
