Small fan like things in glass

[jmsilhy]

Hi everyone, do you know what these are?

They're in a lot of places of my front glass, is this the begging of an algae bloom? Tried to take a pic but it's a little hard, I hope you can see but they look like the top of a feather duster only smaller...

Thanks!

No kidding, they may be mini-feather-dusters. I can't make them out however.

Those green things look like plants. Every one of them is oriented to the light.

And what kind of plant could it be? Can't find anything online, don't know if it's good or bad, or if I should scrape it immediately, or try to capture as much as possible to avoid propagation, you know, very newbie here... lol

Sure looks like some kind of macroalgae to me. May not be able to give a better ID until it grows bigger, but my first guess would be Bryopsis, or a green hair algae of some type.

Whatever it is, start taking control measures immediately before it gets out of control.

What hhaase said ^.

And that means removing from the glass, expelling from the system and skimming the s**t out of it?

I'll review parameters tonight but they seemed good last time, with low nitrates and phosphate.

Keep you posted...
