Algae ID please!

[Kruss7]

Hi all,


Looking for an ID on 2 kinds of Algae I’m facing, very small patches of it but I want to figure it out early.

First is a red hair style algae, it is hard to manually remove it from the rock, it seems to only also be in a lower flow area between my acro colonies.

The second is a green small leaf like algae

Parameters
Phosphates 0.05
Nitrate 5 ppm
Alk dkH
Calcium 430
Mag 1488
Ph 8.16

Can you please provide pics under whites? It will help ID.

Here’s some pics under whites.

the red algae was more solid than the pictures but I pulled some out the other day.

I think the red is Gelidium. Can't make out the green pic too well.

perhaps Red Wiry Turf Algae (or maybe Chondria?) EDIT: I think styx was right with Gelidium

and Dictyota

Dictyota for the green i think

I think you are correct.

OP, it seems we narrowed it down to Gelidium and Dictyota, as always, nutrient management and manual removal will help


Dictyota:

Somewhat easy to remove by hand, or at least to cut down for the cleaners to grab at. Its eaten by some crabs, many urchins, and some the more voracious and multi-algae eating snails (Limpets, Chiton, and some Turbos) (and of course sea hares)


Gelidium:

pretty hard to remove by hand, and can regrow from little bits and spread from them too. Turbos and Urchins (as well as those sea hares) eat it. Some crabs may also eat it.
