I wouldn't be happy with that level of ammonia in my tap water. Is that even safe to drink?"Somewhere, something incredible is waiting to be known." Carl Sagan

Actually, ammonia isn't even something regulated by our state or by the Feds...and my research shows it isn't uncommon in rural wells in our area to some degree. I've read that this level isn't harmful to humans. Probably we have our own "cycle" that deals with it! If I had to choose I'd take this ammonia level over chlorinated water any day.

0Another morning, another round of tests, yet another mystery. I am so not into chemistry!
Ammonia 4ppm per API (can't decipher free ammonia test results)
Nitrites 0.25 (after being zero the last two days)
NitrAtes 40ppm (rising after being down to 20 or less yesterday afternoon)
No ordering fish today!
I'm wondering if the large ammonia load yesterday afternoon - 4ppm after doing a 90% water change with ammonia in my tap water - is what caused the nitrItes to spike up and the nitrAtes to climb? I did dose with Prime at the time of the water change.
I need advice on what to do today. I assume I shouldn't add any ammonia as there's obviously a load in there. Should I do another water change or leave it until I get ammonia/nitrItes back under control?

40g and I added 1 cap full (bottle says 1 cap full per 50g).

0I think the biggest mystery to me right now is the rising nitrAtes. There are no nitrAtes in my tap water, have tested more than once. No fish or fish food, no decay that I can see. There has to be a reason and I'm thinking I have to discover what it is unless I want to do water changes numerous times a week....

The Nitrates rising are just a part of the cycle. If you do have ammonia in your water source, then that is adding to the Nitrites and eventually Nitrates portion. If you are still adding ammonia, then you are still adding the source material for your beneficial bacteria to convert.
I haven't done the chem math of it, but I don't believe its a 1 to 1 conversion rate. So the end output of Nitrates is a higher ppm than your intro rate of ppm in Ammonia.

Thank you, Trilliane, that really helps my understanding of what is happening.
