I will be using this post to demonstrate the ammonia, nitrite, nitrate cycle. Over the next few weeks I will be adding to this post my ammonia, nitrite and nitrate readings on the live rock that I just got in.
If all goes as expected you should see the ammonia levels rise and then the nitrite levels rise while the ammonia levels the begin to fall. eventually the ammonia levels will drop to 0 and the nitrite levels will start to drop. Once the nitrite and ammonia levels are both 0.00 the cycle is complete and the rock is ready for the display tank.
I expect on taking readings every 3 days. This should be frequent enough to get a good range of readings.
Ammonia = 0.3
Nitrite = 2.5
Nitrate = 2.0
Ammonia = 1.0
Nitrite = 0.0
Nitrate = 0.0
Ammonia = .5
Nitrite = .2
Nitrate = 1
Ammonia = .02
Nitrite = .1
Nitrate = 2
I must say I am a bit supprised by the first days readings. I was not expecing such high nitrite. The rock has only been in the water for 4 hours and we already have .3 ammonia. This is not a good sign for a short cycle.
Well as you can see the ammonia has really taken off as would be expected. What is corious is that the Nitrite and Nitrate are not reading 0.00 or close enough to that to make it hard to tell on the test kit scale. I also put the LR
in fresh saltwater today. Effectivly a 100% water change.
As you can see the ammonia levels have effectivly been cut in half by help of the water change on the 21st and also the additional 3 days. The nitrite is on the rise as it is converting the ammonia and the nitrate is also making an appearance again.
It looks like the curing pocess is almost finished. Should have 0.00 readings on ammonia within a day or so. Nitrite will then soon follow. At that time I can move the rock into the main display tank.
