Fighting Dinos for months with no luck...

[zalick]

Edited my post above. I shouldn't type and play with the kids at the park!

The key is how much UV exposure you hit the dinos with which is a function of speed through the unit and bulb strength. For example: if you had a 240w unit, you could run a feed pump at 2400gph and achieve
90,000µw/cm²(EOL).

You want at least 90,000µw/cm²(EOL) to kill dinos IME. BRS said there is some evidence you need even higher exposure.

Here is a link to aquaUV exposure chart. note that this is ONLY for aquaUV units and you can't apply the same to other units.

I battled for 3 months and tried uv, mb7, and peroxide with no luck. I added IPSF reef diversity pack and within 2 weeks was dino free. I'm not sure if it was the added cuc or bacteria diversity but it worked great.

Yes

Would you do anything to the refugium lighting schedule? Turn it up? Turn it down? Sorry

You can leave as is. Dino should not have reached the fuge

Do this:
First- Check phosphates and nitrates to assure theyre not elevated.
Here is full program:
Prepare by starting with a water change and blow this stuff loose with a turkey baster and siphon up loose particles.
Turn lights off (at least white and run blue at 10-15%) for 5 days and at night dose 1ml of hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off.
During the day dose 1ml of liquid bacteria (such as bacter 7) per 10 gallons.
Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX as it is food for dinos.
Day 5,, you can start with blue lights - ramping up and work your white lights up slowly

You need the UV plumbed directly in the DT, pump and return flow.

The 25w is "just" too small for dinos in your size tank.. You need to be turning over the water at least about 3x WHILE achieving the proper UV exposure. For the 25w aquaUV that is 400gph or less, preferably 200gph for that unit. <Edit>So you need a UV unit that gives you 90,000 exposure at 450gph.

The 25w aquaUV housing and bulb length is the same as the 57w. You can buy a 57w transformer and a 57w bulb from aquaUV and voila, you now have a 57w unit. This is what I did with an old 25w unit.

Then with the 57w unit plumbed straight in your DT, run about 700gph through it and your dinos will be gone in the blink of an eye.


*Also, a couple day lights off will have no real effect on your corals.

So I got the 57W transformer and bulb from my LFS who is letting me borrow it. Being that my UV is plumbed on my return line, what do you recommend the GPH I should be putting through it?

I'd shoot for 1000gph or less. I think mine was around 750gph.

But it's far less effective, and maybe not effective at all, to be on the return line. I have a 114w in my sump and it did nothing for the dinos. But when I put the 57w directly in my display they were gone in no time.

Here is the aquauv chart for the 57w. You definitely want 90,000 or higher exposure IMO.

Gotcha so any GPH below 1000 is gonna be above 90,000 exposure correct?

Correct. I believe it's linear. So 500gph will be approximately 180,000

There is a minimum flow needed to keep bulb cool and minimize precipitate buildup on quartz sleeve.

 

[dwest]

I have the 57 watt unit for dinos. I pump about 300 gph through it. Have been doing this for over 2 years. I typically get almost no precipitation on the sleeve when I inspect the bulb every 7 months (I replace every 14 months). As mentioned above, from and back to tank is important.

Could I use the 55watt Jebao UV on my 40 breeder?

Yes, you can use an oversized unit. Just keep an eye on the tank temperature. I would still plumb it in and out of display temporarily.
