Looks like cyano and can be blown away gently with a turkey baster and then siphon up the area and loose matter, reduce lights and add snails such as margarita, nerite, cerith and trochus which will consume ant remaining

Looks like GHA ut im thinking beginning of turf algae. I would place it in a container of tank water and pull off as much as you can by hand and scrub the rest with a firm toothbrush and some 3% hydrogen peroxide.
Return to tank, reduce white light intensity and number of hours of white lighting and add some snails such as :
Astrea
cerith
turbo grazer
trochus

A Pencil urchin

8-10 Caribbean blue leg hermits

Are you using RODI water or tap water from the faucet ?
What is your phosphate level?
Is tank at or near a window?

Your tank looks fairly new- The first six months or so are generally a rollercoaster as your tank matures. You will most likely see lots of different looking algae and bacteria. They call it the "ugly stage."

I use RODI water from lfs and their saltwater, this tank is pretty small ( 15 gallons ) so that might be too much cleanup crew ?. Before this outbreak I had only 1 blue legged hermit crab and a peppermint shrimp. 2 days ago I added am astrea snail and he moved to that rock and I think he is slowly eating it.

I'm not sure of the phosphates as I get it tested at my lfs ( they use redsea test kits ) and they said my water is " perfect ". When I asked for numbers they said " well, everything is zero and kh is 10.5 "

And yeah it close to a window and does get some sunlight sometimes

The tank is about 5ish months old and this only appeared after first corals

So just add a few snails, keep up with weekly waterchanges and let it be ?. I don't mind it TOO much for now

The UV from sunlight was my suspect and can penetrate shades-blinds-curtains.
Do you know what kits they are testing water with- If Api, some may be false as it often gives a zero reading.
I do believe its the indirect sunlight causing the issue. Place a piece of black construction paper from Walmart on the side facing the window and you will see a drastic reduction

They test with Red Sea test kits

Again - the window light is the cuplrit

Okay thankyou, will try out the construction paper
