In sump UV sterilizer, no pump needed

[lelandmarine]

This seems like an inexpensive easy way to add UV to a sump to kill water column dinoflagellates at night. In my case no one would be exposed to it (timer would turn it on at midnight and off at 6AM). Not sure what kind of damage it would do to tubing, plastic, silicon.... Does anyone know how far UV travels under water? Thoughts?

Personally, the idea of just that 'one time' accidentally looking at an exposed 13w UV light while cleaning, etc., would scare me. Not in my comfort zone. But curious to hear what others think. ;Facepalm

I was thinking possibly put it into a t5 reflector and then taping it to the outside of my sump. And then blacking out that section so the light can’t escape. I don’t know if I would trust that submerged for any period of time.

These do work. You might wanna figure out a way to put it inside a piece of pvc and get the water to travel thru. That should keep the light contained

Not sure how hot they get, your idea would avoid that

Agree, that‘s why i was wondering how far the UV travels, if it would degrade the PVC

Don't worry. If you put it on a timer the UV output will degrade pretty quickly.

I'm sorry to say but this is a bad idea that has no way to work.

It takes much more than for something to simply haphazardly pass by uv light in order for it to work.

It would do damage to things you don't want damaged though...
Like plastics, tubes, skimmer, seals and so on.

Bad idea.

Thanks for the feedback

Any idea how far uv travels i water?
