What is this?

Came home to this green/yellow stuff on my glass.

I've never seen anything like that before. Definitely curious as to what it is?

 

[jabberwock]

Can you post a full tank shot? Might be helpful...

 

[gabesreef]

Full tank shot

Full tank shot

Looks pretty good...

Does that stuff move?

Did you use ocean live rock?

Is that side of the tank facing a window?

 

[gabesreef]

No live rock, no window and so far no movement

These look like hydroids. Scrape off with an edge of an old credit card or similar into a net and discard. If not hydroids - algae spores

Do you have snails?

 

[gabesreef]

I have two snails but have never seen this before. I recently replaced the sand bed with live Carib sea sand…. Is this a pest from the live sand?

 

[jabberwock]

I'm thinking algae.

Looks like some sort of hair algae??? I had something similar when my tank was fresh, 2months or so.

I got some turbos and asterias and alot of pods and it just kinda disappeared lol

*edit* if it grows furn line fronds then it could be bryopsis

I guess we’ll see it’s got me a bit worried

 

[AydenLincoln]

I think it’s the beginning of hair or another type of algae especially since it’s green!

ahh nothin to worry about! Tank looks new ish, it's all apart of tank aging. If it doesnt go away in a month or so, or looks like byropsis (you can google it it's pretty distinct) then you can maybe see about taking more agressive action!

Yep, don't worry. Unless I hear water hitting the floor, I don't worry about my tanks.
