Did you look at the results on this thread - where ammonia was added to a 5 gallon tank - with no carbon source - and bacteria depending on the level of ammonia in the tank - were able to decrease it to 0 within a day or so? Many other products did not work - however unless there was an extraneous carbon source. Pseudomonas (shewanella) - I do not believe (but point me to it) use ammonia alone as a food source (with only Co2 as the carbon source). For example in a waste treatment plant - there is a lot of organic carbon.
The only product that seemed to work here was one that required refrigeration and a short expiration date. Which bacteria was 'in the bottle' I dont know. (This is Fritz Turbo 9000). According to the manufacturer - these are nitrifying bacteria (not heterotrophs).... unless I'm misremembering. Thanks for your expertise
Yea i read through all these experiment too And in the experiment i posted there's that product from BI it actually used some kind of chemical to bind ammonia and nitrite that was why it's experiment show weird color result. It actually is a chemical reaction not biological reaction. But sorry that my native language is not English so hard for me to share everything I learned from my study. But it is true that there's some product that doesn't work and some do.
And also Hay bacillus is also a common product that's put into these bottle to help with nitrifying. So due to it's impossible to know what they put into the bottle we just need to be more patient when it comes to cycling tanks i believe.
