I'm still far from sold on the bacteria in a bottle, be it snake oil or if it expires on shelves, too much inconsistency for my liking.
At the end of the day, ghost feeding isn't a good way to cycle a system. The pure ammonia or cocktail shrimp methods are better, to which I prefer the shrimp method as it is 'set it and forget it'.
If you dosed the tank to 2 ppm
of pure ammonia, the answer here is to wait and watch. Nature will finish the cycle. Patience is key in the hobby. Keep testing and watching. If it goes under 2 ppm
ammonia dose again. Then when you dose 2 ppm
and it and the nitrite levels are not detectable in 24 hours you're ready for fish. There is an article in the article section that talks about cycling as well.
