OK, got my Jebo 18W UV hooked up to my 45g. Wondering how often you use it?? I also plumbed it in series with my Phosban reactor, Thats ok, right?

I too have my UV plumbed into my phosban reactor as phos media and UV's usually require around the same flow rate.

I run my UV 24 hours a day when I introduce a new fish, and then hardly ever after that unless my fish get stressed out or if I have a fish that is particularily prone to ich.

I do the same as Stones. I turn it on when I get a new fish then ,if needed, I set my timer to turn on the uv once the tank lights go out, then off when they come back on about 12h on & 12h off. I like the night cycle because the main lights are off & there isnt extra heat added to the water at the same time with lights on. If you get my drift!!!! Thats the only time I use mine is when adding new livestock. I have mine plumbed off my return (dart pump) with a valve to control flow then back to sump.

Leave that on 24/7, cause Jebo's are junk from experience. It didn't kill anything and I even had algae grow on the glass tube lol.

Contact time is dependant on your flow rate across the bulb.
