Need help to id algae. Never seen it before

[tfass16]

Hi guys. I have a one year old 40g tank. I am getting an outbreak of long green strings throughout my tank. It is on the substrate, rocks, heater, snail shells, you name it. I tried every cuc almost possible (hermits, all snail types, tuxedo urchin, tomini tang, lawnmower blenny) and nothing wants to eat it. Please help and thankyou

my first thought was bryopsis, but i don't see any of the tell-tale fern-like tips. and especially since you stated nothing eats it. my second guess would be chaeto, but i've never known or seen it to cling to rockwork or sand like that.

Exactly. And thats why its so hard to start a treatment without proper id

If we could get more clearer close-up photos under white light, it would greatly help with an identification.

Almost looks like chaeto

This looks a lot like Chaeto! My other guess would be Cladophoropsis, that is the closest thing that I could think of, and would fit with the nothing will eat it

Very intrigued myself looks similar to what I'm dealing with. Although mine is a new tank and not as sparse as what you have, mines much thicker. Feels almost synthetic / hair like. Very tough and almost rough.

Although on further look... i don't know not a clue. I'm too new at this, could just be normal GHA by my eye ahaha but very strandy and tough, unlike other GHA in my tank which comes off by a simple scrub with sterile toothbrush... Sorry to hijack / jump in lol. Free bump?

This to me looks quite a lot like Cladophoropsis. This is a image of what it looks like.
