I'm using ammonia at the moment to recycle my tank after unexplained fish deaths. I started off by adding enough to give a reading of 1 ppm and dosed this every morning. My ammonia is now dropping to zero within 12 hours of dosing...nitrites were at 0.3 last night (3.0 the night before).....hopefully be zero tonight.
It's only taken me a week to get to this stage, but this was because the tank was already cycled (I'm just simulating an increase in bioload). If all is zero tonight or tomorrow I'll do a 50% water change and add 3 Chromis.
Does this sound sensible? (Sorry to hijack your post with my own question!!!)
