Abstract

Nitrogen and 0, transformations were studied in sediments covered by Lobelia dortmanna L.; a combination of
15N isotope pairing and microsensor (0,, NO,-, and NH,+) techniques were used. Transformation rates and micro-
profiles were compared with data obtained in bare sediments. The two types of sediment were incubated in double-
compartment chambers connected to a continuous flow-through system.
The presence of L. dortmanna profoundly influenced both the nitrification-clenitrification activity and porewater
profiles of 0,, NO,-, and NH,+ within the sediment. The rate of coupled nitrification-denitrification was greater
than sixfold higher in L. dormanna-vegetated sediment than in bare sediment throughout the light-dark cycle.
Illumination of the Lobelia sediment reduced denitrification activity by -30%. In contrast, this process was unaf-
fected by light-dark shifts in the bare sediment. Oxygen microprofiles showed that 0, was released from the L.
dortmanna roots to the surrounding sediment both during illumination and in darkness. This release of 0, expanded
the oxic sediment volume and stimulated nitrification, shown by the high concentrations of NO,- (-30 yM) that
accumulated within the rhizosphere. Both ‘“NZ isotope and microsensor data showed that the root-associated nitri-
fication site was surrounded by two sites of denitrification above and below, and this led to a more efficient coupling
between nitrification and denitrification in the Lobelia sediment than in the bare sediment.

I’m inclined to agree with duanes that this is just semantics. It seems like father fish is just talking about seeding vs no fish cycling. I’m not a patient person, so I always seed and add fish immediately and it always works. I don’t know how I feel about adding stuff from nature, seems like a good way to introduce pathogens, parasites and pollutants.

I have never been able to understand why LFS do not sell tanks with a basic air driven pump and sell every tank with an air driven filter. Each one being one from their own tank setups which can have been running for months. They cost practically nothing to run for the LFS and go some way to help seed a new tank.
Even if they sell a mechanical filter too. Or at worst use the air driven filter media in the mechanical filter for the newby.
most folks don’t have a spare filter media sat around waiting to be used on their first tank setup.

I guess if your balancing guppies then this could work. Sounds like he's wasted his whole life on deep bed filtration and just had this epiphany...

Nah, I checked out some of his other videos and it looks like he’s been preaching this for a while now
 
Regardless of how simple seeding a tank with seasoned media is, I think every keeper should know and understand the nitrogen cycle and proper water parameters. Today's idiots would love a simple fix-all like a magic rock from the drainage ditch outside that makes them successful keepers without even having to think. That's what it's coming to these days...people are too lazy to even think lol. But I digress.

I somewhat agree, I haven’t really worried about the cycle much in a long time. I do understand how it works but having access to media and decor and bottled stuff for freshwater and LR for salt, I don’t have a need to concern myself with it. Personally I would never take something out of a creek or lake and put it in my tank. I don’t really worry about parameters either. I have a solid maintenance schedule and beyond that, my fish tell me if there’s an issue by how they look and act. If i do see a problem then I’ll test everything to figure out the source of the problem. It seems to work, I never lose fish to anything other than the occasional ( very occasional) jumper or an unforeseen compatibility issue
But where I agree is newbie’s should not do what I do until they learn all the basics and get that eye for noticing a problem before it’s a noticeable problem

Technically, it seems to be bacteria and archaea and seems to vary in different conditions. As an evolving subject of research I try not to get overly excited over any single particular study, nor a youtube video saying "biologists claim" with comments by one biologist of unknown credentials (and one computer generated biologist). For example, a 2011 paper says both bacteria and archaea are involved, with archaea dominating in most but not all fw aquarium setups.

Aquarium Nitrification Revisited: Thaumarchaeota Are the Dominant Ammonia Oxidizers in Freshwater Aquarium Biofilters - PMC (nih.gov)

Then a 2021 paper comes along, says this "previous research" overlooked Nitrospira (a bacteria) and states:

Microbial community analysis of biofilters reveals a dominance of either comammox Nitrospira or archaea as ammonia oxidizers in freshwater aquaria
