Recently setup my 120g that's been cycled for about 2 months. Meanwhile, I'm putting everything through QT, fish, coral and inverts. Inverts and coral in same tank, fish separately.

Anyway, coral QT is a 10g with a HOB, heater and powerhead and A160we. This tank was not cycled. Filled it with fresh SW added some dry rock from my cycled 120 and dosed some biospira on top. Last week put in zoa and Monti FRAGS. Thursday added CUC from reefcleaners. Yesterday noticed some greenish-brown stuff on the frags. Today it's all over the frags. So far seems to be isolated to frags.

What is this?

Salinity 1.026, 76F, 450ca, 1350 mg, 7.5 alk. Phosphates 0.13 nitrates 20. I'll be doing a 50% wc tomorrow to bring phos and nitrate down. Using Tropic Marin pro salt.

Possiblely cyno

That tank is beginning to cycle. Manual removal is the best option

If can grab some tweezers and pull some out. Hard to tell from the little spots near the frags.
you have the right course on lowering po4 and no3. You might want to try a small amount of gfo in a media bag, water changes dont help much with po4 as it does with no3. Just enough to get you under .1 should help with that algae and let the corals out grow it.

I tried blowing it off with a small baster pipet. It gets some of it off but a good half remains stuck. Zoas really not liking it. Some are closing up.

I would try snails. Banded tegulas work well with a variety of algae and are very meticulous about clearing an area unlike some snails. They are also quite small.

after acclimating place snails on the plugs. Let them do their thing.

I've got dwarf and Florida ceriths, nessarius, trochus snails in the QT with the coral frags. Gonna try to get some small ceriths on the frag rack.

They could be what brought it in. There is not much for the CUC to eat right now I would manually remove it and not add any more CUC.

I droped in algea wagers, pieces of nori and put in reef frenzy frozen. Let settle. Hermits ate the frozen, snails went after the nori and algea wafers; think they'll do OK.
