Diatoms. Cyano. Dinos

[KnH]

Not sure, thinking cyno, added some more dry rock pukani. It’s mostly on the new rock but is starting to spread around. Best pictures with a filter lens. The sand is mostly brown with a little green. The rock is dark purple. Really Bubbles up as the day goes on. Just Upped my light intensity, 6-month setup, High nutrients NO3 50, PO4 0.8. Did water change and added more Chaeto. Added a skimmer breaking in now. Ordered more CUC

Do you have a microscope? It's invaluable when troubleshooting algae/cyano/diatom/dino challenges.

Is present first thing in the morning? Not the bubbles, the film.

How many gallons is the tank

The number one thing to change is the degree of lighting you are using for open rock surfaces, it should be lowered until all that is packed in coral.

Or at least aged enough that it's covered by higher forms of life (visible or otherwise) that prevent the nuisance stuff from gaining a foothold.

Viewing reef tanks as an unending turf war really helped me gain an understanding of how to deal with nuisance stuff and coral placement.

I’ve noticed the few scapes absolutely covered in coral flesh to the exclusion of all visible rock surface have given invasions literally no place to implant

coral flesh other than zoanthids and leathers is largely completely algae excluding. I’ve never for example seen a frogspawn get algae on the polyps, I’ve never seen a lobophyllia with bryopsis on its flesh portion. No mushroom coral I’ve even seen had algae on the anemone part. Being covered in coral mass is exclusive to other attaching organisms it seems.

coralline has this same ability to repel when it’s thick on the rocks

Yes it was there this morning

90g with a 20g sump

This is what I could get. Doesn’t look like any of the other pictures I’ve seen

Redid my attempt less magnification
Salifert. Definitely not low nutrients
PO4= 0.5
NO3=50
Ostreopsis. ?
