I literally did this a month ago and saw 20% reduction in free ammonia in 24 hours on day 27. Can you link me to original article? I saw what I saw but would be interested in reading more about it. I would rather not get drawn into the personal attacks or anything just want to read the article.
Here's a difference between aquabiomics and what you likely did...
"
set up two identical tanks with each type of rock, and arranged these randomly on each shelving unit. I filled each tank with sterile-filtered (0.2 µm) UV-sterilized artificial seawater (NeoMarine - Brightwell Aquatics) prepared at 35 ppt using RODI water. In addition to the rocks, I added 4 lbs of dry aragonite sand to each tank.
Throughout the process, I was careful to control the microbial community introduced into each tank. For this reason, I sterilized tanks, equipment, sand, and dry rocks (but of course not live rock!) using bleach or hydrogen peroxide. While setting up, maintaining, and sampling these tanks, I sterilized my hands with bleach to minimize cross-contamination."
But I think this part is even more key...
"For the next month I continued to measure water chemistry and sample for microbiome testing,
leaving the lights off to avoid algal growth during this period."
Did your tank circulate in the dark for the month? Or was it lit / in a lit room?
The reason I think that may be more important than the specific differences in sterile techniques, is that there are very few organisms that can actually nitrify - oxidize ammonia to NO2/NO3, but uncountably many that can take up ammonia photosynthetically.
Maybe literally 1000's of times more species of organisms that can process ammonia photosynthetically than chemoautotrophically.
