Need help identifying a dinoflagellate

[Ronk1109]

Hi everyone need a little help first identifying a dino and then a best way to combat it. I was running my nutrients way lower than I should have. No3 was 1.1 and Po4 was .02

Forgot to mention that this started in my sand bed and has now spread to my rocks also.

Dinoflagellates - Microscopic ID

May I add this here, considering I currently have dino’s to deal with. It may be useful to anybody with identifying, although there are lots more strains I believe. Images from left to right are identified below.

Thank you. I have that picture list. I’m going crazy trying to match mine. A few of them look so similar and I don’t want to make the wrong decision

Is it short strands or long? No strands? Just mat like appearance?

 

[Lancelogan1217]

In most reef tanks we see the big 3. Prorocentrum, ostreopsis, amphidinium.

 

[Lancelogan1217]

Amphidinium has no strands, low bubbles. Usually found in sand beds
Ostreopsis is long stranded.
Prorocentrum are very slimy and short haired.

this is ostreopsis. Some of the cells are smushed and the contrast in the image is weird.

Not sure if I loaded it in the slide correctly. Hopefully I did. First time using a microscope

And it was plenty good to ID the dino. Great job for a first shot.
I was just explaining why the cells appear different than that pipe normally does in pictures posted here.

and after going back and looking at another sample a lot of them are turning in a small circle which definitely looks like ostreopsis. Only thing is they do not completely disappear at night. Could it be a mixture of different types? And I have a 57 watt aquaUV running around 1500 gph. Should I slow that down to less than 1000? It’s a 180 with a 40 breeder sump.

If it's not a type of dino that goes into the water column at night the UV sterilizer won't help. I have my UV at about 700 gph and it killed off all ostreopsis but not the dinos in the sand.

Thank you. I have my uv set wayyy to high gph. I’m going to have to dial it back or get a second one temporarily. I’m slowly going bare bottom so I’m sucking sand out along with the dinos. Hoping that will help.

I used this guide

Dino-X will clear that.

For dino's in sand ive always heard to keep no3 at 5 ppm and po4 at .o5 than dose with silicate, and phyto. Essentially ur causing a diatom bloom that would out compete the dinoflagellates for nutrients.

Thank you. I’ve dosed myself up to no3 8ppm and .08 po4 it goes up and down a little with water changes. I just ordered phyto and brightwells sponge excel so I’m hoping this will all get the job done.
