Got this from scraping glass is it Dino or something else?
Lotta crazy something else. It’s a fast swimming phyto. I’m thinking tetraselemis maybe. Not a nuisance Dino for sure.

Hello everyone! I been reading this page to inform myself and was wondering if anyone could give me an id.

@taricha I took some samples today and did all the tests you mentioned on post 986 and 987 but couldn’t get an ID do a fellow Reefer helped me out with his microscope...
amphidinium.

Get something hungry. They are quite edible, and their blooms wouldn’t last.

Something like what? Sorry I’m pretty new to this world
Sorry. Many microinverts in a tank ought to eat those things. The actual advice is just to let it ride out. It shouldn't last long. If it stays more than a couple weeks, then let's rethink it.

Wouldn’t using something like waste-away and extra nitrifying bacteria help get rid of them? In theory something like waste-away would eat it and then the nitrifying bacteria should overpopulate the tank and possibly outcompete it?

One, This isn't known as a nuisance
Two, we wouldn't have experience with which methods are helpful for getting rid of it
And three, resorting to bottles of cure can cause much larger disturbances than the organism itself.

In one of the videos taken on the microscope I do see something eating it
Excellent. Just let it ride. If it's still a huge annoying population in 2 weeks, you can revisit the idea of intervening.

I decided to turn my lights off for the next three days. I have my tanks in my room so I shut the shades turned all lights off ect. Its not a complete blackout but im curious to see how this will work for my small problem. Has anyone tried this? If there is some progress I will try a complete blackout. Is there any other steps I could be taking? Thanks!

Ok so I won’t do anything to battle it directly but can I go ahead with what I was planning on doing like seeding copepods and some plankton? Or would that be a bad idea?

Can anyone ID from these pics? I will try to get better ones this weekend. Thansk! The last pic has a black background, zooming in helps see better.

Added my green killing machine this AM to fight oster Dino.

my question is, I’ve been dosing some PO4 & NO3 to no real advantage.
growing some GHA, but my Dino’s are much more.
PLUS I’ve lost 4 fish in 2 days. I run a skimmer and carbon.

what might be the cause of their death?
small fish.

I dont have access to a microscope and was hoping to get some feedback from the community. Based off of the pictures below, are you guys confident this is Dinos? I personally thought it was cyano and treated the tank with chemiclean but it had 0 effect on it.

Any feedback would be appreciated!

I don't think anyone can say for certain without a microscope picture, but I will say this and please understand I am not IDing your pics, but when I had Dinos (ostreopsis), it looked very much like your pics. A 55watt UV filter and siphoning through a filter sock daily and turning off powerheads for a few days to keep them from blowing around was my first line of attack and it made a big difference while I worked on my nutrients and biodiversity afterwards. I would recommend trying to get a cheap microscope or see if anyone in your area is here on R2R and has a microscope that can help you ID what it is that you have and that will help you try to get the situation under control.

Thank you for the prompt response. This will give me some direction. I'll look into purchasing a microscope as well.

Think I might have Dino's.
Newish set up ~ 3months. Came home after a weeks holiday (2 weeks ago) to find some GHA growing and what I thought was diatoms. I have a few LPS and had target fed them once a week before going on holiday.

However after reading though about half of this thread pretty convinced they are dino's and not diatoms. its like a brown dusty covering but goes deep into the gravel, pockets of air also and smallish strings. Seemed to have also migrated onto the back and side wall.
Checked Phosphate with a hanna ULR and measured 0.01 and Nitrate 3.0ppm. Other parameters which have been rock steady for the past 6 weeks are.
Alk 7.0
Ca 450ppm
Salinity 34.4ppt
Mg 1540ppm
Ph8.2
Temp 25.3-25.4C
Nitrite 0
Ammonia 0

I didn't have a microscope until today but as Phosphate was 0 I started dosing with Seachem Phosphorus and also Nitrogen a couple of days ago. Didn't go mad as wanted to check that it was dinos first. Phosphate was dosed at .02ppm for my tank volume and has so far risen by the amount I've dosed i.e. doesn't seem to be being used, now sitting at .05ppm but struggling to get nitrate to rise, (will be getting another kit to double check this). Dinos seem to have taken off.

Anyway Microscope arrived today and here's a pic and video below - think it is amphidinium if someone could confirm please. This sample was from the gravel but a scraping from the back wall also showed the same.

true, but if I were a betting man I'd bet it was dinos.

indeed, a small-cell amphidinium dino.

Okay. Re identified as oster Dino’s after microscope.
bought a 24w green killing machine to upgrade from my 9w for my 75gal.

Nitrates at 10ppm
PO4 at 25.

very little light.
after a week of UV.

more Dino’s than ever before.
