What type of algae is this?

[Boyceez]

This algae is growing over all of my rocks and i have no idea what type i️t is??

Here are some more photos, it’s a light brown algae covering basically every spot on the rocks and it’s growing over all the corals... Any ideas on a possible id and a solution?

I had this on my rock recently also. Can it be removed with a toothbrush? My LFS said it is a nuisance sponge and the experts on here agreed. Both said it will not hurt anything but looks bad. I can imagine it will start hurting coral if it over takes them but never let it go that far in my tank. I scrubbed it off a few times and haven't seen it since

Okay so i should scrub i️t off and get rid of i️t

Yeah why not. It will make your stuff look better. Let me know how it turns out

Update, i got home and scrubbed every bit of rock i could with a toothbrush, starting to think i️t is calothrix after doing some research.

Could be the start of hair algae or dino. Every time you do a PWC
