Found this little patch of algae growing on my powerhead and figured I would be safe and make sure it wasn't anything too bad.

Me thinks its the bryopsis.

+1^ fern like structure makes me agree

Ok I am going to go and scrub the %*^% out of my powerhead now.

I actually believe it is derbesia. Is it slightly hard or totally soft and mushy? If the latter I would definitely say it is derbesia. A PAIN in the behind!

 

[Fishninja]

It is mushy.

Don't leave it in the tank. If possible take the rocks that have it out, toss some Peroxide on it (if you can without hitting corals), wait 10 min, scrub, rinse thoroughly and put back. You will have it disappear in a week. it might come back 2/3 months later and you will need to repeat. Also need to check what is causing this and address: high nutrients, excess light, detritus accumulation, etc.

Derbesia
Derbesia marina is a small whispy green seaweed that forms soft, bright green, filamentous tufts. The filaments may reach up to 3 cm in height. The filaments are usually laterally branched and arise from a basal creeping system which penetrates the substrate. Filaments lack cross walls except at the bases of the branches.The gametophyte life stage of this species is known as Halicystis ovalis and is club-like, spherical or with small bladders. It is attached to the substratum by slender rhizoids (Burrows, 1991)

There's several Derbesia btw, all green algaes. No?

This is how my tank once looked.

Tried everything, until I stumbled upon the Peroxide thread, and nothing worked.

One day after treatment

One week. I could not believe the results.

Bryopsis.

I believe there are several yes. Some people can get rid of it relatively easily, but I did not had such luck.

Theoretically derbesia is easier than bryopsis to get rid off. But it is still nasty. To me it looks much more like derbesia.
