Please help to ID (and get rid of)

So I was fighting with Dinos - and obviously PO4 and NO3 has been elevated. While Dinos are still a problem (slightly better now) all my corals got covered in some form of algae which is killing small colonies within days. Blaster does remove a small layer, but the thing looks hairyish and seems to be stuck to the base of the polyps. A lot of polyps have detached from mild turkey blaster waves (which never happened before). A bit lost in what’s going on and what should be the next steps.

PS:Yellow tang and a fox face are not picking at it at all, neither do shrimps or snails...

Please post a picture under white/neutral light. It's hard to see under blue light and the actual color can help with the identification.

Thanks! Attaching pictures under white light - zoas and the damaged torch (the one on back detached within a day =()

Looks like the start of bryopsis.

May I ask how old the tank is?

The substrate looks quite new and the green coralline algae is also common in new tanks. Is it possible you are simply going through the ugly phase?

System is about 3y.o, the tank has been upgraded in April so it had new substrate. The "clean" substrate comes from cleaned sand that got syphoned while fighting with dinos...
I wouldn't mind the uglies, but I've lost half the zoas I had already, 2 torches and a hammer (all getting covered like these polyps on the pic)...
