Dark brown stiff algae - what kind ?

[Abhishek]

Hi ,

I have these dark brown stiff algae all over my tank . Now all my acros are thriving but these dark brown stiff sometimes look horrible .
PO4-0.05 and nitrates - 10-20 .

What kind are these algae ? Some form of GHA ?
I have a few snails - trochus and turbo . What will eat these buggers ?

Regards,
Abhishek

Polysiphonia sp.

It looks like some type of red turf algae IMO. (Callithamnion?)

So what's the best coarse of action ? Mexican turbo snails ? Rabbit fish ?

Any help ? Still do not have a concrete id on the species and what will help.. Have over 10 tuxedo urchins but they hardly make difference .
