Dosing With Ammonia, How Often?

[Paul70]

My ammonia levels are now reaching 0-0.25ppm in 12 hours. Can I redose straightaway at 12 hours or should I only dose evry 24 hours?

My nitrites are curently +5ppm

24 hours only. Test at 12, dose at 24.

thanks m8. it was last night at midnight when I tested at 12 hours so was in 2 minds whether to dose again or not. I held off though cos i'd seen somewhere on here that 24 hours was minimum but I had been told something different by the dude in the LFS!

Glad I waited though. thanks again

Test by daylight if you are doing liquid tests, the yellows to greens for ammonia can differ quite a bit in standard house lighting.

You don't need to be doing 12 hour tests until your nitrite(NO2) is dropping from 5ppm to zero ppm in less than 24 hours.

The 12-hour testing is basically for the 3rd phase of fishless cycling, the phase after the nitrite spike period is over with.

Agree with WD.

Many thanks folks. Will save me some money only testing every 24hrs instead of 12.

Was well pleased this morning when I found my ammonia test to be lovely and yellow rather than a hint of green. nitrites still +5ppm tho. I suppose the n-bacs take longer than a-bacs to develop tho.

patience will get us there!

Your right Paul, the N-bacs on average take twice as long to develop than the A-Bacs.
