true. who cleans their socks daily?
this was the post I was referring to...
Fishkeeper mentioned in a PM he later ID'd the new ones as amphidinium. From my experience, not a super toxic type. If I had Ostis, and could trade them for amphidinium by running UV - I'd do it every time.
They are 10 micron and changed them daily while I had the dino's.

That's what I used: 10 micron sock .. it was disgusting and got clogged constantly... it was POOL size too.
I won't try that again.
I won't try that again.
I do still want live dinos - even more if they are toxic. I'll send you a PM with my shipping info.
Dfee,thanks so much. I got your sample a few days ago, put it under the scope that night.
Saw almost exclusively diatoms. almost nothing living.

the brown discoloration in the rag was also diatoms

took many samples, and after a lot of looking I am uncertain. I did find a few weird clear shapes of similar size and shape repeated often enough to make me wonder if it was the theca (armor) that came off of a dead dino.

then I found a brown pigmented blob of similar size and shape that bore resemblance to a dino

short vid changing focal plane. there's some sort of dino-like structure to it.

I didn't post while I tried to look for possible IDs. Didn't have much luck there. While it's an unusual shape, there are a lot of lumpy shaped dinos...

Over the last 3 weeks or so I've done around 10 siphons of the sandbed.
One would expect to get less and less gunk out when it's done this frequently, but that is not the case.
The amounts are simply amazing every time.
I took a closer look at the lightest particles and found one type of special interest.
It has the color and similar shape to my ostis but is more uniform, larger and they don't move.
I kept wondering if these are cysts so I melted all the calcium based particles off just to get that possibility out of the way.
It surely looks organic.
Being in their millions in the sand that is close to solely inhabited with dinos it's tempting to assume they are cysts.

Hmm , interesting. I guess that's good news. Thanks again, Taricha. The reason I thought Dino and not diatom was because they get worse throughout the day and also after water changes. I guess water changes could fuel diatoms and I just found out diatoms are photosynthetic. I didn't think they were
My take is that you indeed had a dino bloom at one point, and they have since receded, to be replaced - on the glass at least - by diatoms and green film algae. I take it as signs that your tank has turned the corner on your pest. All good news.
But, I would expect any soon attempt to starve out the diatoms/green film would cause dinos to reassert themselves.
Well, I haven't had long brown snotty dinos in about a year. So if they are indeed diatoms, how have they not consumed all their food (silicates) and died out by now?

when they die, they release the silicates back? It's a closed system unless you extract them with skimming or water changes.
I'll get pics up soon, but it looks like majority ostreopsis, although the first one I got pics of was actually prorocentrum now that I look carefully at it.
In the sample from robertifly, found some prorocentrum
One of those elaborate shaped dinophysis(?) that we never get to see in our aquariums
But mostly lots of ostreopsis. Likely o. Ovata. They were pretty well scattered from the shipping, but there were lots of them all over.

three days since lights have been back on...no dinos in sight...yet!
hoping I have gotten rid of them for a while...two sps rtn'd during the 4 day lights out, I suppose it was worth it though, if I can keep them from returning. On day three, vaccumed out sump/detritus with shop vac and did large water change. Also bumped my alk up to 10, to try to keep Ph up. I can't say what has resulted in my small success so far...last time I did lights out they came back like crazy a day later...will let all know if they return. Oddly enough, my coraline algae has exploded during the lights out period.

I'd guess your coraline is doing good because you corals are miserable and most likely not growing at all.
Two of them were is such a bad shape that a short darkness finished them.

It's been a few years for me.

Nice pictures.
I've got hundreds, after way to many years, from a futile battlle.
