Promoting Maximum Biological filtration growth

[uselessmidget]

This question has always burned my brain, I understand the nitrogen cycle but, I have always wondered if UV light helps to increase growth of Nitrobacter or Nitrosomonas bacteria?

So if I were to have 2 identical filters on 2 identical tanks except one tank had uv light directed inside of the filter, would it have more bacteria? less? same?

Thanks.

Less,
Depending on wattage and flow it could be as little as none.
UV is an equal opportunity killer. It will take out helpful as well as less desirable bacteria.

Interesting thank you

Ammonia Oxidizing Bacteria (AOBs), including the Nitrosomona genus and a few others, do not rely on nor utilize photosynthesis in any way… thus no form of UV light will hold any benefit to them…
　
Nitrite Oxidizing Bacteria (NOBs), including the Nitrobacter genus and a few others, do not rely on nor utilize photosynthesis in any way… thus no form of UV light will hold any benefit to them…
　
UV sterilizers produce UV-C rays, which will kill bacteria and are harmful to any/every form of life.
　
Most species of AOBs and NOBs prefer dark places over light…
　
When discussing the nitrogen cycle we should keep in mind that there are species of bacteria outside the genus’ Nitrobacter and Nitrosomona that are AOBs or NOBs… Actually there are microorganisms that are not even bacteria (e.g. Archaea) that can oxidize ammonia into nitrite.
　
Using the terms “AOB” (Ammonia Oxidizing Bacteria) and “NOB” (Nitrite Oxidizing Bacteria) are more accurate…
