ID help please - Macro or seaweed?
 

Hi all,

Just got a bunch of this but I can't positively identify what it is.

It could be Gracilaria, Halymenia, Porphyra or even Nitophyllum...or just red seaweed :lol:

The texture of the plant in question is very slippery and the blades are flat. All of the blades stem from one fat blade at the base. It is not attached to any rock.

The first picture is without the flash.

If I'm going to have any of this stuff in the aquarium I want it to be beneficial (such as an excess nutrient absorbing macro) that will reduce pest algaes.

Right now I have it on a clip in the aquarium. I do not have a sump or refugium.

Any help on this would be appreciated. Thanks.

It's red halimenia. Great stuff, but it loves iodine & great for nutrient export.

Thanks, Anthony. I knew you'd know the answer.
