Cladophora? Spirogyra?

One of my resin wood caves is growing algae, but what type is it?

Looks like hair algau

Further thought, Staghorn algaue.

Hmm, i'm trying to grow algae! But I'm trying to get it to grow on my rocks for my Hillstreams to munch over.

I think it is possibly this as well. The strands should be greyish if it is (it is a Compsopogon sp., and a Red alga, Rhodophyta). Cladophora and Spirogyra are both green threads ( and Green algae Chlorophyta).

Its a kind of dark green.

Hi all,
Now "dark green" is a tricky one, if it had been "grass green", it would have definitely been a green algae (Chlorophyta), but dark green doesn't totally discount "Staghorn algae" which is a red algae but appears dark green / grey. Is it physically tough, like a nylon thread?
