Why would you dose bacteria after a water change?

A reason to dose good bacteria is because not all bacteria grow at the same rate. Nitrification bacteria far exceed the rate of growth of facultative or denitrification bacteria. Given the dynamics of these differrent growth rates, certain good bacteria are crowded out of effective population densities.

This link gets into the science behind the role of differrent bacteria and enzymes in a marine enviroment. These microbial overlords make it happen. Just ask the Martians in "War of the Worlds".

As I said in the post and as the scientific articles describes in detail, nitrifying bacteria will exponentially multiply and consume the carbon source before the facultative bacteria.

I've seen papers saying otherwise.
Do you have more of a peer reviewed paper and not one from someone selling a product?

Yolly416 here's a good thread to read through covering various carbon sources.

For most reefkeepers that use skimmers, denitrification is unnecessary. When any bacteria grow, they absorb nitrates and phosphates. Therefore carbon dosing with protein skimming removes bacteria in the water column, thereby removing nitrate and phosphate. However, because they are in a high oxygen zone they would not be faculative bacteria as tmz says on the first post of the thread linked.
I discontinued protein skimming twenty years ago. I rely on denitrification bacteria for nitrate export and macro algae removal for other nutrient export.
Considering that protein skimmers, at best, remove 30% of DOC (dissolved organic carbon)
I use activated carbon which removes 70% of DOC.

Facultative do not require low or high oxygen environments. That would be obligatory bacteria. Facultative can be aerobic and switch to anaerobic. Some prefer one or the other. Carbon dosing with acetic acid or ethanol is thought to feed that type of bacteria among other organisms.

Faculative bacteria live in low oxygen or no oxygen environments. Faculative bacteria perform denitrification with free nitrogen gas as an end product.

Many good and bad Including cyano
Each carbon source goes through an oxidation process or metabolized (some manufacturers like those for vinegar call it fermentation) by a particular type of bacteria and has a particular metabolite.
Like ethanol
Metabolism
Hepatic enzyme alcohol dehydrogenase
Metabolites
Acetaldehyde, acetic acid, acetyl-CoA, carbon dioxide, water

When I recently saw this post, I said the bugs win. As a bioreactor, the OP feeds bacteria and carbon as he observes nitrogen bubbles exiting the reactor. How cool is that.

If you look at our posts we are talking partly the same thing.
No worries. At 68 years old, I may be a little crusty. Add to that, I am a Cajun Aggie with a degree in Marine Engineering. To top it off, I have a Class 4 certification in waste water treatment, which qualifies me to consult people on how to stir S.H.I.T.
this is an instant classic post
