H is at the start. Im week 5/6. I had my ammonia spike and drop and just finished my nitrite spike and drop. It is a second ammonia spike.
Prime doesn't get rid of ammonia it changes the chemical makeup by binding molecules to make it less toxic for a period of time. I don't remember the exact process at the moment. I believe an ammonia test will show both the free (toxic) and bound (less toxic) ammonia.
It sounds to me 1 of 2 things are happening.
1. you are adding to much ammonia for the size of the colony of bacteria
2. you do not have enough bio media to support a large enough colony to convert the amount of ammonia.
both equate to the same thing, you do not have enough bacteria to convert all of the ammonia to nitrate.
Something bad happened. I changed the water and added enough to register between 1-2ppm 24 hours ago. As of now, no change so it looks like something killed my ammonia fixing bacteria while my nitrite fixing bacteria were growing. Very strange. The only variable other than adding ammonia was temperature. I don't think I added too much ammonia. We had a hard freeze a couple weeks ago. It didn't freeze in my garage but Im sure it was in the 40's so I expect that did it.
