Please help, dynos or diatoms

[ArmyReefer]

can’t tell if I am battling diatoms or dynos. Nothing on the corals, mainly on the sand bed but it is on some rocks. There is no long snot but rather very short strands matting the sand. There is a couple spots on the rock that has tiny bubbles. Debating if I should black out the tank for 72 hours or if I should doze dyno X. Had my father in law look under a microscope and he sent me the attached drawing.

been digging deep for changes I have made in the past 30 days. 1 took a rock from my nano tank and put it in my display, and I took my refugium offline. I took my refugium offline because I went to rotate it and it all fell apart. And I noticed my phosphate had jumped super high. Have new clean chaeto coming tomorrow to put it back online

Tank is over 2 years old.
salinity 1.026
Alk 8.2
Calcium 430
Mag 1340
Nitrate 8
Phosphate .011

Have you removed any rocks or biomedia lately? Also, did these appear after or before the phosphate spike (and your following decrease of it)? The center one is a type of dino (at least from my understanding).

It sounds like dinos .

Based on your father in laws sketches you do not have diatoms. You do have nematodes ( the worm like creature) , ostreopsis (maybe a problem if too many), a snail like creature ( I have them and they don’t seem to cause a problem but I don’t know what they are), and probably other types of dinos.

Dinoflagellates – Are You Tired Of Battling Altogether?

I don't know what percentage of folks had luck battling dinos with any of the methods in the old Dino thread but it's obviously a very low percentage, so I'd like refresh folks on the natural alternatives and lay out three areas of info: some of the factors that contribute to a dino outbreak...

Seconding @Wampatom , applause to your father-in-law.
The sesame seed shape ostreopsis is the main concern.
(The snail shell shape is a foraminifer, harmless)
