I am sure that carbon dosing will have some impact on autotrophs. I am skeptical about the downside being significant, given the experiences reported here. I think we're done, pending data on what is happening. That data is going to be very expensive to produce, I'd guess, which is too bad. It'd be interesting to see what's happening.
How the the ammonia-processing capacity might increase very rapidly in response to the input when carbo dosing is stopped?
The only way to do so is stop feeding which is advisable.
It is a fact that autotroph nitrifiers need 15 days to double there nitrification capacity. If this capacity is brought back to 15 % instead of 60% because of carbo dosing it will take one month to reach the normal capacity needed.

All data is available as heterotrophic ammonia and nitrate reduction has been researched thoroughly during past decennia in university's all over the world. I have used research of Ebeling, J.M., Timmons, M.B., Bisogni, J.J., 2006. (Engineering analysis of the stoichiometry of photoautotrophic, autotrophic, and heterotrophic removal of ammonia–nitrogen in aquaculture systems. Aquaculture 257, 346–358. https://doi.org/10.1016/j.aquaculture.2006.03.019)
to help develop my point of view. The publication can be consulted http://www.baharini.eu/baharini/doku...onium_reductie

The suppression of autotrophs by heterotrophs is a key factor in managing mixotropic biofilters and part of most studies about this subject. I advice to read some of these studies.
