Diatoms or Dinoflaggellates please

Hi guys.

Can anyone help me identify this. I've been battling it for a few months. Thought it was diatoms, so I changed my rodi filter resin. Output of tds was 2ppm. Now 0 ppm. Nothing changed. If anything it got worse.

Phos is 0.00 today usually quite low
Nitrate is around 0.05. Usually very low too.

It is not smothering corals thankfully! It blows off very easily, but its back within hours. Half way back within the hour!

Could anyone suggest a not so expensive microscope that might help me identify it.

Most likely Dino’s, especially with basically zero nutrients…

Yes. Brown snot, dinos.

Thanks guys.

Any ideas on microscopes to id the sucker? As I mentioned, my coral is fine. The dynos won't stick to it or grow in it. Would that narrow down the possible species?

Cheers

Unfortunately that doesn’t help. You can hrab a cheap microscope off Amazon for $15-$25. Post a pic here on R2R and you’ll get some good help with an ID. If you blow it off the sand and rock at night with a baster does it seem to stay off u til the lights come back on? If so a UV sterilizer would be a big help, not a magical cure but a shove in the right direction.
