Does freshwater kill dinos?

[living_tribunal]

I've been working on eradicating a nasty dino bloom in my qt frag tank. Many of the frags are ready for display and I'm wanting to move them over soon.

I've been attacking the dinos with just about every method:
- UV Sterilizer
- 1ml hydrogen peroxide (10g tank) dosed twice daily
- 3 day blackout
- dosing nitrate/phosphates
- dosing bacteria (fritz turbo start)
- dosing pods and phytoplankton
- turkey basting the crap out of them

This has proved beneficial in removing most all of them and I'm ready to move some of the frags that are clear of spores to my display.

I want to be on the safe side since my display is a relatively new system and dinos would wreak havoc on it. I've read numerous places that freshwater immediately kills dinos (not spores). Does anyone have the science to back this up? It's hard to validate many ideas you come across on the forums and elsewhere. There's too much conjecture to parse through. I just want to make sure I'm providing adequate treatment to the frags with my dipping process before transferring to their final tank.

I have been able to find some data on the efficacy of freshwater dips on certain dino strains but they don't cover the one I have: http://agrilife.org/fisheries/files...mportant-Parasite-of-Cultured-Marine-Fish.pdf

Freash water dips do not kill all types. Some will become encysts until being put back into salt water for a while. Other do the same thing with H2O2 dips. I believe Taricha did this experiment. I have wondered if a freash water dip followed by a H2O2 dip would work though, because you'd be sure to use the dip that worked on which ever one you had.

I also read post when Taricha intentionally put some dinos into an uninfected tank and they just moved to the water column and never bloomed. As long as they are an environment with nutrients, they will not bloom. So even if they were introduced, that system would be safe.

I did two freshwater dips, 45 seconds each, and did hydrogen peroxide dip on their skeletons. I didn't feel comfortable dipping them into 100% hyrogen peroxide 3%.

It's kind of funny, and I guess contrary to popular talking points, but I've been dosing my two week old tank with nitrates and phosphates. After this dino bloom, I'm never going to let those nutrients hit zero again.

I've also been on a crazy biodiversity bender with multiple microfauna and algae, amphipods, 7 different copepods, daily phyto dosing, 5 different types of bacteria, worms, pygmy brissle stars, coralline seed, and other stuff added to the tank this week.

My though is that if you can keep your nitrates always in between 5-10 and phosphates between .05-.15, your biodiversity will just flourish and dinos will never have a chance to take off.

This experience has been eye opening to say the least. I'd rather deal with bryopsis and bubble algae at the same time than dinos.

Will update shortly on if the two freshwater dips worked. I have osteo and potentially small amounts of amphidium btw for reference.

I did mean 3%. Thanks for the clarification. Not sure what 100% would do.

Any updates here? My coral QT has amphidium. its a 10g tank so I'll happily tear it down... just trying to figure out the safest way to "clean" the frags before I move them elsewhere. been considering both H20 and H2O2 and would love to hear how this experiment panned out

I had an astraea snail with dinos on its shell. I took it out and dipped the shell only in freshwater making sure not to get water inside. Used a tooth brush. Put it back in tank and guess what showed back up almost immediately: dinos. So freshwater didn’t work for me.
