    I have been cycling a 75 gallon for a week and I know I have some time to go. However, I was wondering how high should I see my Nitrite go? My Ammonia is dropping very very slow and my Nitrite has risen to 2ppm. The 2ppm and 5ppm colors are so close so I did a half strength test with tank water and tap water and the results appear to be closer to 2 than 5. However, if I started out with 1.5ppm of Ammonia, how much Nitrite can I expect. Is this normal?
    I've only added the ammonia as Dr. Tim's instructs not to add ammonia if Ammonia or Nitrite reading is above 1ppm.


    Using Ace Hardware Ammonia
    8/12/19 - Add Ammonia 5.0mL = 1.5ppm; Add 8oz of Dr. Tim's One & Only
    8/13/19 - pH = 8.2, NH3 = 1.5, NO2 = 0
    8/14/19 - pH = 8.2, NH3 = 1.5, NO2 = 0
    8/15/19 - pH = 8.2, NH3 = 1, NO2 = .25, NO3 = 0
    8/16/19 - pH = 8.2, NH3 = 1, NO2 = .5, NO3 = 0
    8/17/19 - pH = 8.2, NH3 = 1, NO2 = 2, NO3 = 5
    8/18/19 - pH = 8.2, NH3 = .5, NO2 = 2, NO3 = 5

    well, it looks like it’s stsrting to cycle

    The short answer is who knows

    It’s all going to be how fast the bacteria populate the tank. In the last three fw tanks I set up I had very little in the way of spiking. Ones I’ve had in the past skyrocketed during the first month or so. I’ve never used dr Tim’s, I’ve used the marine land in fw and never saw any spikes after it started eating ammonia

    in another week or two your nitrites will be sky high, over 5ppm.

    the test will max out at 5ppm, you'll do a 50% water change, test again and it will still be testing over 5ppm.

    Is that normal? Dr Tim stated if ammonia or nitrite goes above 5ppm, then do a water change. However I thought the whole reason for not adding more than 2ppm ammonia is so the nitrite does not go above 5ppm. Plus wouldn't going about 5ppm stall the cycle.

    high nitrite did not stall my 2 fish in cycles. and i had a high nitrite spike due to an improper Purigen regen. all 3 times, the tank completed the nitrite phase in about 3 weeks time.
