How long to run UV Steralizer for Dinos

[ArmyReefer]

So I have had an issue with Dinos for 6-8 Weeks. I have bought and installed a 25W Aqua UV temporarily plumped into the display.

The two questions I have are

1. How long after Dino's are gone should I keep the UV plumbed to the display? It is around 90% gone at this point, but plan on plumbing it to my return once Dinos are gone.

2. That last 10% does not want to go away, are there types of Dinos that will not be eliminated by UV?

I can only tell you what I do, and I run a UV all the time. It went on at Dinos, and hasn't been turned off since. Well, except when putting in certain supplements, etc.

So I plan on running it 24/7 but plan on it being plumbed from my return into my tank. You kept yours plumbed in your display? I don't see how I could do that and not have it look like crap. It sits in the main room in my house, and aesthetics are important for this tank.

I have mine plumbed from the return pump and the outlet from the UV is connected to the return line on the display, so it stays down in the sump. I was very particular in how my display was going to look. I didn't want anything more than 2 MP powerheads in it.

Yep, that’s how I will plumb it as well. But while trying to beat these Dino’s, have it directly in and out of display

I don't think there is one answer to how long. I would give it six months.
Amphidinium stay mostly on the sand and rock so UV is not effective.

Mine is an AIO, so I put it in the back compartment, so you don't see it in the main display.

Are you sure the last 10% is Dinos, blue lights make everything green and brown look the same. Just a thought.

Yes, I actually turned off the UV sterilizer and ran Chemi clean for cyano as not doing water changes and raising my nutrients caused a pretty good outbreak. It was starting to really effect my corals. During the time I had my UV sterilizer off they came back with a vengeance. After 48 hours I did a thorough cleaning with my 20% water change and turned everything back on.
