Hello, I was testing my 12 gallon tank for nitrites, and I noticed that while testing in the test tube, I would initially get a reading of 2-4 ppm. However, as I left the solution sitting in the tube, for about 5 minutes, it would drop down to .5-1 ppm, and if left longer, say about 10 minutes, it would drop down to 0 ppm. Is that a sign that my tank is done cycling? Whenever I left the mixture in the tube before it would always stay at the same level, if not get darker.
My ammonia levels are at .25 *but I'm not worried about that, mixed in pure ammonia earlier in the day up to 4 ppm, and in about 6 hours it dropped down to .25* Nitrate levels are 5-10 ppm.
I'm a little surprised because just yesterday the nitrite levels stayed at a steady 2 ppm, with no change, and it's only been a little over 2 weeks since I started this tank. I also did start using sea chem stability the other day though. pH level at 7.4-7.6
So verdict? Is it done cycling?
*edit* I also have found a baby snail. Still too small to figure out which species, but judging from where I got my plants, most likely its a golden mystery snail. Huzzah for free snails!
