nice to know that 13.5ppm of nitrite results from 5ppm of ammonia, explains why it can be off-the-scale at a 12hr test but at 0ppm at 24hours , was always a bit stumped by that

glad your finally processing the ammonia Tropical Chris! welcome to the nitrite spiking stage!!

Thanks for the replys guys & girls had a full drop on ammonia when i tested today so topped upto 3ppm like waterdrop said.

How do i go from here now? do i carry on with the 24 hour tests etc?

Just want to make sure im doing things right

thanks again people.

Yes, usually we do 12s and 24s at this point and if your nitrite keeps hitting zero ppm at 24 hours you should proceed on up to 4ppm, then 5ppm.

There has been a climb in p.h is this something to worry about or not?

Also wanted to ask about the Nitrite. What should i expect from this now? will it climb further or stay at this 5.0 level? just want to know what the spike will be so i know when its happening

Sorry for all the questions.

Thanks guys.

Day 34 updated.. Any clues as to why the p.h keeps bouncing from 7.4 & 8.0?

the A-bacs convert the ammonia to nitrite (and i think I read some of this includes nitric acid?) anyway this causes the pH to drop, the ammonia itself causes pH to increase, so it will tend to go up and down as a result, I did some pH tests before adding ammonia at 24hrs and after adding, and the pH does notably change a bit.

the nitrite should stay off the scale (the API test kit measures up to 5ppm) so it will remain >5ppm until your N-bacs grow to a sufficient amount to start processing the nitrites, this part is usually the longest part of the cycling process, and it happens quite suddenly

Cheers for clearing some of that up

yes, agree with yaninullah's post except its nitrates(NO3) that have nitric acid as a component, not nitrite(NO2.)

Going to start testing on 12 and 24 hours now.. should have started a few days ago but was waiting on my shifts to change at work.
