Thats not enough magnification for me to ID, but sometimes just the movement alone can give some hints. Are the cells moving?
I should plug my website: http://www.algaeid.com/ Here you'll find photos and videos of different dinos. A tiny bit of info on treatment options....
I was referring to Billme's photos. Yours, Zesty, do look like dinos. I'd love a sample too because the growth habit appears similar to the dino I...
Ballgame, dinos can look like your photo. How old is your tank? Have you added new sand or new rock lately? Diatoms appear the same way as dinos (at...
I'm still around and still IDing dinos. Your photo looks like bubble algae and some other macro algae. That should be much easier to get under...
I don't know UV sterilizers well enough to recommend one. As a hobbyist (rather than a biologist), I can say everything I've heard is that most being...
Like most of these benthic pest dinos they migrate into the water column at night. Wet skimming at night or UV at night will kill some of them. They...
That is Ostreopsis. A dinoflagellate that makes Palytoxin. You'll notice that they tend to move around in circles around a tether point. I have...
I could only indicate whether it was a dino or not (and no better than any other member of this board). And even doing that from a photo is...
Between the color and what look like actual filaments instead of just globs I think you have cyano. Much easier to get rid of if it is cyano. You'll...
If the color is accurate I'd be more inclined to say that is cyanobacteria.
Could also be cyano. Have you ruled that out? I've been able to ID some of the more obvious dinos from pictures taken through a child's toy. I've...
It's hard to count if they are moving around
I am a reefkeeper (just 3 years now) and a biologist studying dinoflagellates. I saw a number of active threads here where people were struggling...
