What is usual level of amonia in its pick during cycling?

[newhobbist]

What levels you had when cycled your tanks?

1 ppm all the way to 2 ppm

 

[Jchillin]

I had the same...maybe even as high as 2.5.

 

[krap101]

well i did mine at 5ppm...

 

[SerLunchbox]

my peak was over 6 ppm

slackers.

mine was off the charts for a couple of weeks

 

[NewFishGuy]

mine hit 10 ppm for about a week and a half...

I did a fishy cycle and kept NH3 to below 2 ppm with water changes.

Ammonia levels over 6ppm will stunt the bacterial growth, hence why 5ppm is the max recommended for a fishless cycle, and typically drops to 3ppm once you're moving into the nitrite spike.

I cycle with fish and amonia level is 1.2 and still slowly growing (it's been 2 months since I started my tank). Should I feed my fish more to get amonia higher faster?

5.0 in my 110 for about 2.5 weeks

My ammonia spiked up to 10 ppm during the initial fishless cycle....but my tank cycled in only 2 1/2 weeks.

Then I added fish and my ammonia stayed at 0 for 2 months and now I'm having all kinds of ammonia problems.
