Yet another N cycle thread
 
Hey all -
I've been graphing all my info from my water tests since I started my ten gallon tank about a month ago, and I was wondering if you guys could check out my reading to see if all looks atleast semi-normal.

I've stopped using the pH Down after finding out that it's harmful to the tank's inhabitants (several live plants, two male guppies, three ghost shrimp, and an unknown number of snails).
Thanks for any help/general comments/advice/ect!

Can you post them in a way that makes them easier to read, am brainfried, trying to understand that.

From March 2nd to March 15th everything is fine...
You get the initial ammonia, then by March 13 the high Nitrite spike which then dies off leaving just the Nitrate.

March 15-19 is the worrying part when the ammonia comes back and stays...what did you do on those days?

Yeah, sorry about the chart fail... I uploaded it as a pic instead.

I haven't done anything about the ammonia, and save for the possible adding of a plant or two, anything that goes into the tank gets put onto that chart. I moved the tank from home to my dorm on 3/4, which would have been a near total water change. The filter media and gravel stayed plenty wet, though. Any chance that could have done it, or could the tap water in my building have any ammonia?

It is possible the tap water caused it if you did not use a water conditioner. It could also have been caused by disturbing the substrate during the move and change, it does not take much organic matter to breakdown to cause ammonia.

Test your tap water and see if you get a reading for ammonia.

You should as well, always treat water with a water conditioner when making water changes.

Sorry again, I just remembered that the .25ppm ammonia might be my bad readings - I use the API Master Test Kit, and the yellow for 0ppm is EXTREMELY close to the yellow-green for .25ppm - it makes it very difficult to tell the difference sometimes.

I'll test for the ammonia in the tap water, and I always use conditioner when any new water goes into the tank :)

Okie dokie... So I just did a comparison with water directly from the tap and tank water. The tap water has little to no ammonia, while the tank water has a very slightly greener tinge (to the extent that it's hardly noticable) than the tap sample.

Hello, I too have a newish tank thats in its 5th week. Everything is going well but when I test the water which is on a daily to every other day basis with my API master kit my ammonia readings are ALWAYS 0.25ppm!! at first I couldn't tell if it was yellow or yellow green but to be honest its definitely more green and closer to the 0.25ppm mark. it never changes, it doesn't go up, it doesn't go down..... so I am wondering if this is actually correct or just a quirk of this kit??

Nitrite is ALWAYS 0ppm and nitrate is between 10-20ppm

I have to wonder, rhy.
So I finally got around to doing what I probably should have done to begin with and tested the water out of the tap. After out-gassing all tubes and testing them, here're my readings:
pH: 7.4
Ammonia: either 0ppm or .25ppm
Nitrite: 0ppm
Nitrate: 20-40ppm
The newest city water report I've found says the N out of city taps should be in the 6-8ppm range, so I'm at a loss for why it's THAT high.
