Backyard Aquaponics
A place to discuss aquaponics

This is a new tought that recently struck me as I prepare for the BIG build

The 4" cap top is cut off an suspended by the supply tube. Thus exposing the water in thin form to the sun uv filter. And also a secondary airiation "waterfall"

Good idea, but if you get into UV sterilization you will see that a minimum exposure intensity and duration are required to be effective. Generally speaking UV doesn't actually kill anything, it damages the RNA or something like that and destroys the ability to reproduce.

I don't think casual exposure will be enough to make a difference. UV sterilization lights will have a recommended flow rate (exposure time) based on the wattage and the target organism. I believe lighter exposure for algae and more intense for bacterial organisms.

I see. Not beneficial. Thanks for promoting research and maybe an experiment.
Airiation? Since I don't use a mecanical device, I should grab all the air I can get even though the fish are doing fine with what I've got. But perhaps the roots could use a bit more.
As always thanks for your input.

dtstjohn, would you please have a quick look at this and translate? https://pubmed.ncbi.nlm.nih.gov/12038489/
In my simple mind, it says benefits? Just a brief reply is all that is needed (I think) please.

UV radiation both helps and inhibits the health of bacterioplankton. Most phytoplankton is sensitive to UV-B radiation and shows distress even at ambient levels of UV-B. A survey of various algae was conducted to understand photosynthesis.

Those are the main points that I see. No results of the survey were shared in the article.

Thankyou kindly
