UV flow rate to kill dinos? UV classic 57

[Mafiaboy]

I am just wondering what other people are using as flow rates, the website suggested flow rates are kind of insane and i've read countless threads with contradicting information.

I'm currently battling a dino problem in my tank, I was dosing NOPOX and it went away then I stopped with NOPOX and went back to ROWA.

I setup a classic 57 watt uv currently running at 920gph. I have a 260 gal tank (including sump) and the dino issue seems tough to battle, I'm wondering if i should lower the GPH for more contact? At night i can see the dino is no longer on the sand and comes back to the sandbed when the lights go on, so it's clear it's the free floating kind.

Anyone have experience with this UV in a similar size tank?

thanks

I keep mine under 400gph for to work on parasite control.

I run the same UV at around 650 Gph (I believe it's rated for up to 1,066 Gph for parasites, so anything less and you're getting longer exposure).

Why does Uv website want 2000+ GPH to kill protozoa ? lol

Needs to be very high flow rate. Protozoas reproduce quickly AND they're not super resilient to UV. Run it high, always or Dinos. Here's the method I use to get rid of dinos in 8 days, it includes a UV sterilizer run at high flow.

Been running a Ultra Violet 57W on a 225 since Sunday to battle Dinos. Pump is a Ecotech Vectra L2 running @ 10% via Mobius. All Dinos are gone...........................for now.

Will add that I've been dosing MB7 in the morning and Food Grade 12% perioxide at night.
