What is this feather duster like plant/algae

[jmsilhy]

Hey everyone, I hope you’re doing great and staying safe!
These started to appear in my glass. Very new system, barely a month but parameters are all good with 2.5 Nitrates and 0 Phosphate (all others at 0, and Mag, Cal and All where they should be).
Thanks

in advance!

Now I’m also finding this in my tank, looking at the whole picture, any clearer idea of what it is? Parameters this morning:
Ammonia 0, Nitrites 0, Nitrates 2.5, Phosphate .25, calcium 440, Mag 1350, Alk 7.7 (rising it slowly to 8.3 with daily buffer). Small CUC with a few snails, micro crabs and a shrimp.
My lights are barely on, in acclimation mode at 20%
