Do nothing is still my strategy. YMMV

1ml of peroxide is good for 10g water each 12h?

Thanks

I used 10ml in a 40 gallon tank. It didn't do a damn bit of good. I've read but can't confirm that it breaks down in about 8hrs.

I've got some very good leads for you to play with.

Today I took a quick look to see if the internet has come up with a solid solution for the dino epidemic and was disappointed to see it seems to be lost and confused.
With all those people with the same problem we should the further down the road already.

I've been able to keep my tank dino free for a very long time and to grow montipora successfully, but my test acropora frags usually fade away in a few months.

Even when the tank had no visible dinos at all I was able to make them reappear for a single day with two methods.

The first one was quite a surprise since I added only about 1 gallon of fellow reefers tankwater to my own and the following day I had a single patch about one square feet and the following day after it was gone for good.

The other one was an experiment that I was quite confident that would bring dinos back. I had been running the tank in algae based mode for the duration, but elected to give GFO a go at the accumulated algae in the display tank and to see if it would help with the sps. Over the years I've noticed that when you replace the GFO media there is always less of it to remove than it was before and if you put your sandbed in a bucket and leave it there for some weeks the white sides of the bucket will turn brown.
I opted this time to use more GFO than usual and not to throw away the dust that comes out with new media as I've always done and for a single day I got most of my sand covered with a thin layer of dinos. The following day I could hardly see them and then they where gone. After running GFO for a month or two the dinos slowly started to show up as the GFO in the reactor dissolved.

I've noticed that the tank is generally doing better when the skimmate is greenish rather than brownish and as some of you know iron is known for red coloring in nature so that has been in my spotlight as a player for dinos for quite some time. I can speculate that iron is vital for dinos or the effect that iron has on the water chemistry can cause a dino bloom or the combination of these or something entirely different is going on, but I leave with saying that iron is a major player.

Have fun!

Ive had the dinos receed for several months after chemical treatments and then out of nowhere the dinos blow up once the N & P levels bottom out.



If you beat it with dino x....thats great and your the first person ive met who beat dinos with this product.

Just an update, my tank is still dino free after treating with Dino-X.

In a old tank I successfully used Diflucan to treat a bad out break of byropsis being dino is a type of algae could the Diflucan eliminate dinos?

I haven't read any reports by anyone who has tried fluconazole on dinoflagellates, not that I can remember, anyway, and search didn't turn up much. You could try it, but I wouldn't count on it working.

I'm now in control of my Ostreopsis dinoflagellate blooms.

This was accomplished with GFO being added or removed.
I had been having dinos in my reef tank for years.
First time this happened I took the GFO out and it took about two months for the dinos to vanish.
My findings got posted here, but people seemed to prefer to keep their heads in the sand.

Next time I added GFO in again I totally expected to have dinos showing up again and sure they did, but it took them around two months to get close to bloom levels.
I took the GFO out again and it took the same time for them to fade away. It's this delayed effect that makes it so difficult to spot GFO as a culprit.

The third event was a flash appearance when I let the fine dust from a freshly added GFO in the tank unfiltered.
I'ts so difficult to get repeated results so this certainly looks like a proper solution to dinoflagellate blooms in our reef tanks.

This result was not a shot in the dark, but years of hard work.
Somehow I think reefers will still prefer to ignore this solution and rather take shots in the dark at something else.
At the same time we need reefers to verify this result by trying it out on their dino blooms.

A study by Dana Riddle points out the iron in our GFO filtered reef tanks is mostly in suspended particulates and not dissolved.
Those particulates are bound to hit the bottom at some point just where our not so beloved dinos like to hang out.
This is why I think iron could be a major player..

Thank you, DNA, for all your efforts to help hobbyists solve the problem of dinoflagellates. From what I've read, it's a very difficult problem to solve, because of the wide variation of treatments to combat the wide variation in dino species. I had some luck using UV for my outbreak.

To sum up what you've said in the last few posts, removing GFO from your system has shown to eliminate dinos. Awesome!

Would you care to give us bullet list of your favorite solutions? I, and many others would be eternally grateful! Thanks again!

That's interesting. Have you ever tried iron supplementation on its own, to see how that affects the system? I wonder what's actually happening.

No, but I might do the opposite and try aluminium based phosphate media, just to prove my point even further. Since I'm in control I don't see a good reason for further tests right now so there could be a long wait for it.

I also think we should open our eyes for the possibility that cyanobacteria blooms could have the same driving force.

FWIW, I rarely have used gfo but have spurred on dino/cyano out breaks by heavy over feeding.

Iron is necessary to their existence as it is with most all life. However, since most can benefit from photosynthesis iron plays an important part to the synthesis of chlorophyll. Deplete iron and you hinder their ability to do so. Keep in mind this also applies to other photosynthetic organisms in your tank like corals or anemones.

I do dose a diy iron citrate solution regularly for my ATS. Does not seem to effect my cyano/dino population which is not noticeable currently with the naked eye.

i am new to this hobby.
Please see here for the progress I long thought that the brown stuff was diatoms. But when they were persistant i beleive i may have dinoflagellate's i have upload the video could you please confirm it
If they are! what is the next course of action.

Well that may explain why I have dinos starting in my tank. I run GFO and recently started dosing Red Sea Coral Colors 4 supplement pack. Bottle "C" is Fe(iron) & complementary metals.

So did you restart your tank., installed UV and/or just eliminated the use of GFO to get rid of the dino?

DNA I also thank you for all your efforts and hard work in helping us all control these beasts. I have read all or most of the posts here. If I am correct you feel that the presence of the dino's in the tank is primarily caused by iron in the GFO or in some other form.
I have been battling the dinos for some time. Never did the scope thing to see what type but they are. They don't show in the sandbed until lights have been on for a few hours being my main identifier. I have had mild success using DINOX and other chemical additives but they clear up and return soon after. I do not use GFO anymore. So what could be the source of iron fueling the dinos? Your thoughts are welcomed.
