Dinoflagellates – Are You Tired Of Battling Altogether?

[Mattyreefs]

Got home today after being away 6 days. Tank was pretty much on complete auto pilot. Tank looks as clear as it did immediately after 3 day blackout. Sand is pure white, no dinos to be seen. This was the first time I stopped dosing bacteria, phyto and silicate and things look really good.

Bad news is I have a few patches of bubble algae and bryopsis that seemed to pop up out of no where. One spot of bryopsis is really thick so I can see it getting out of control quickly of I don't get on top of it. Not going to test anything until tomorrow but I'm curious to see where N & P went.

Any id on these?

Hi! Someone can help me with ID and solution?

since two months, i've push up no3 at 50 ppm and po4 3.5, run a Little bit of ozone.
a few months ago I was 100% sure it was osteropsis, now after the treatment I wrote above, they seem much smaller to me the microscope is at 10x

thank you all.
p.s. uv never worked in my aquarium

I don’t think you have to keep phosphates and nitrates that high. I guess not many corals are in there so you are going to be ok.
anyway I think you have Amphidinium. Silicates dosing works as a treatment.
there is tread dedicated for this type.

Amphidinium Dinoflagellate Treatment Methods

This thread is a spin-off from the @mcarroll very successful Dino thread The purpose is to discuss methods for removal and fighting against a particular strain of dinoflagellate - Large Cell Amphidinium. It seems to make up about a third of the cases of dinos. The reason this strain gets its...

I have had aquarium since I can remember. Ok the very first one hardly can be called an aquarium as it was just a 3l jar with a 2-3 inch catfish in it my dad caught while we were fishing. And that fish didn’t last long with me as he had to go back to the river Danube. It was growing faster and...

Ostreopsis the most of it. The round ones might be Coolia

That was my initial reaction as well, however, some users thought it was all prorocentrum. I added a UV yesterday and I could already see a difference.

Not sure after looking at it again but UV works for both as far as I know.
add activated carbon too

When you decide to start corals again…
If corals are not the objective at the moment you can starve dinos more from traces…

Cool, thanks. Should I turn off my calcium reactor then? Been keeping dkh @ 7.5.

Also, should I vacuum the Sandbed?

I understand you are keeping longer without corals: if that’s the case then yes you can turn the reactor off but keep testing (coralline, spirorbis etc consume more than we imagine).

Stirring the sandbed often is a good thing, not necessarily vacumming.

How’s the overal situation over there?

@taricha Has anyone tried introducing tunicates, salps, or krill to a dino infested tank?

Yea I have it turned down quite a bit now that the corals are dead but also want to keep coraline etc growing, I'll keep it where it's at since it's stable.

Ok I'll start stirring it more.

Slightly improved? Not all gha is gone/dead - some is still thriving on a few rocks. Some rocks are completely clean now which is nice, they are on one side of the tank (which is odd). The other side has more short gha (some looks dead, some alive). I took a toothbrush to it all today.

Dinos are still very present. I've been dosing mb7 each morning turning off uv and skimmer for 4hrs (per directions). I've been blowing off rocks almost daily, might have missed a few days. No3 and po4 have come down into acceptable ranges - 8 no3 / 0.12 po4

Keep on trucking! If I could beat them so can you.

Since our dinos are not planktonic, but benthic (sand/algae/surface associated) these organisms are not likely to help.
There are some ciliates that will eat dinos, and some tiny crustaceans that are seen munching the less toxic ones - but these are not usually cultured commercially.

Hi All, hoping to receive a positive Dino ID. Please see the updated video and images, summary and parameters below.

I have been battling for around 4.5 months now in my 15g reef. Lost around 70% of my corals and many inverts. I have tried raising water temp to 82 (currently around 79) without success, same with reducing the photo period to 8 hours. Did one course of DinoX which did not really help substantially. There was a green hair algae issue, with thick mats on the sand bed, but this has now been replaced by red cyano. I am doing manual removal with a filter sock 1-2 times a week which seems to be helping. Also, trying to avoid water changes, only do a small one (20%) every 4-6 weeks. Current parameters are below. Any guidance highly appreciated. Thanks!

ammonia 0
Nitrate 40
Phosphate .23
Alkalinity 6.1
Salinity 1.025

 

[ggNoRe]

I can't help you ID. But I would suggest doing Elegancecorals dinoflagellates regimen. That coupled with a UV helped me to beat a very stubborn dino outbreak.

the dino in the video is ostreopsis.

Thanks! What method(s) did you use?

@Reef and Dive - should I dose mb7 daily until they go away? I ask because the mb7 instructions say to dose every other day after the first two weeks. Also, any thoughts on the elegant corals method? Was thinking maybe I should do that too?

 

[RobinR87]

Hi, can someone ID these for me please?

I THINK it's prorocentrum. Tank is a cube 20. https://www.reef2reef.com/threads/w...ome-journey-and-effort-for-redemption.855559/ = Build thread.

Not sure how to tackle this.

 

[Reef and Dive]

Yes. Done before. Works for amphidinium not for Ostreopsis. It is pretty radical.



I believe there’s no method that will totally wipe out dinos… So when they are not anymore in plague proportions just keep the good management…

MB7? Just often, not every day…

Prorocentrum to me… it seems the flagella arise from a single flagelar pole, with symmetrical morphology and a very marked pyrenoid. @taricha agree?

 

[taricha]

Prorocentrum to me…

yep!
