The point isn't to exterminate the dinos. It is to develop an immune system by introducing their predators. They will always exist in small concentrations, but never reach infection or plague levels.
I wonder if a large water change from a mature tank will work. The idea is to extract as much of the dinos and then simultaneously introduce the micro biome of the healthy tank.
I agree 100% with these statements.
I am presently helping a fellow reefer battle a dino problem, his is a new system that he started with dead rock and 2 inches of caribsea seaflor special that he seeded with some live rock , he let the tank cycle for a few months then added some fish and a cuc. He thought he had a persistent diatom bloom and asked what I thought, I put a sample under the microscope and saw Ostreopsis Ovata. He has no coraline algae to speak of, no green micro algae on the glass and half of his sand bed has turned solid. We started slowly removing the sand bed and began the dirty method, his po4 and no3 are not detectable, began dosing phyto and pods and running 10uM filter socks, stopped skimming and water changes and only running 1/4 the carbon.
It's been about 3 weeks now and things are looking much better.
My problem started after decimating my micro fauna with algae x.
I am now 22 weeks dino free, back to my 200uM filter socks, doing regular weekly water changes, still dosing 400ml phyto daily and culturing and adding pods regularly. Po4 is .04 and no3 is 6ppm, coraline algae is growing strong, tank and inhabitants look great.
I had Ostreopsis Ovata, battled for a year, dirty method is what worked for me.
I was wondering if someone could help me out.I have had a successful reef tank for many years and just upgraded recently to a reefer 450. I sold all coral except a few pieces. I used all my old rock and added new sand.

So his tank had no corals in it? Just fish and clean up crew and he still got dinos? I'm still debating whether I believe all tanks have dinos or if it has to be brought in from an infected tank.
One thing I noticed when I did have dinos was that my sand also hardened in several places. I didn't really know what to attribute that to, I thought maybe it had something to do with my calcium.
Many microbes can spread very well on its own. I wouldn't spend much time worrying on how a tank got infected with a dinoflagellate. I suspect this one was there from the start, and grew into a plague when the conditions were right, but that's only a guess.
