New algae growing in tank

[Philt56]

Can anyone identify this algae that has started growing in my tank. doesn't seem like hair algae. The bigger pieces look like thin blades of translucent grass from your lawn. This is a new tank about 4 months old. I have 2 xr30s over the tank Red Sea 425xl.

I started a fuge about 3 weeks ago with chaeto under a kessil h80 fauna led and also have been dosing phytoplankton. Not sure if there is a relationship there? The chaeto is growing well. My margarita snails are eating it a little but not making a dent. Planning on adding an algae blenny since I don’t want it out of control. It’s pretty but don’t want it taking over.

The good news is that the cyano that was on that rock and adjacent piece had been going away. I did a water change and vacuumed the cyano in the sand. I had been blasting the rock with a baster to blow the cyano off the rock.

Thanks!

That’s hair algae without a doubt. What I would do is get aquatic plant snippers and you can snip the algae short to keep it, it will spread slowly unless your snails eat the new areas forming. But it will soon spread. Try using the algae water stuff at your local pet store! Gl!

Algae water stuff? You mean an algaecide? Wouldn’t that kill chaeto also? I thought hair algae was much denser, finer hairs and darker in color.

Please don't use agecide and I'm not sure if it's even hair algae. Don't waste money on plant snippers. #reefsquad anyone seen this algae before?

It almost looks like Green Gracilaria but it isn't branching enough to be what I am most familiar with. Very odd looking stuff!

Chlorodesmis Sp. Green Marine Macro Algae ? Kinda looks like it.

Thanks all for the responses. It just started recently on this dry pukani piece.

Wow! Poisonous to coral and some fish?

Not sure about that. Mine looks much more delicate, flat blades vs stringy or wire like

I've never heard of it in a reef tank, but maybe Halodule wrightii?

Better closeup. I just noticed with the nice weather that the sunlight in my roof shines directly in that area. Also sea grass sounds like this may be a candidate.

Ulva sp. Perhaps Ulva flexuosa or Ulva intestinalis

U. flexuosa

U. intestinalis

Do not do this, if you cut it then it'll just float into your water column and go everywhere, if anything, yank it out and make sure to really pull out the roots too.
