I run it 24/7. I’ll wait it out a month or so and see what happens
Run it only at lights out, 24/7 will kill other photosynthetic competition.
I am at the 11 month mark with dinos, and switching UV to lights out time only has helped.
However, UV doesnt do much to amphidium which is a sand dwelling Dino.
Siphon into the sump through a high micron filter, keep nutrients up, and maybe get your traces up.
I've known for a long time it's recomended to stop dosing traces, but I started dosing small amounts of chaeto grow and I finally have green and coraline algae growing, which helps some with my dino problem. I also use the marineland magnum in tank canister with the high micron, that helps me a lot bit may also be ineffective with sand dwelling dinos.
Maybe reduce light intensity if you can, while aggressively siphoning them out? Avoid having to add new salt water though, they also recomend stopping water changes, again that may not be the best way to deal with them. I've seen some comments on Randy's florine dosing thread where people claimed it ended their fight with dinos as an unintended conciquence, so we may see a big change in the strategy of fighting dinos.
I also think flow might be an issue, if you can crank your up. Try that too... maybe. Reef Beef a month or so ago did a piece on dinos and they say it's not even a thing for them, they change some parameter to shock the system, a little bit of lights out and changing flow, that's been the trick for them, but they also mention they get ahead of it quick, most of us don't.
Who knows, Dinos suck, and thrive in the same conditions our corals do so.... fighting them is not a science yet.
