Macro Algae ID

[GMay]

Hi all. I'd like to get some help identifying some of these algae. I know what genus many of them are but some I just cannot place. I am including some pictures.

Specifics
Live rock from gulf live rock.
Tank 28 gal JBJ Intermediate LED. Full lighting 8.5 hrs per day.
Tank has been running for about three months.
sg 1.025
Temp 80F

The algae I'd like to ID are the brown ones, the green feathery one, and the broader leafed red one. All came in with the live rock so they will native to the Florida gulf coast.

This is still a work in progress and I like the color the plants bring and they also help to maintain good water conditions. NO3 has been at <0.2 ppm and PO4 <0.03 ppm since the tank got up and running.

I will be sharing plants with those that would like some, if it is not too difficult to ship.

Wow, you have a lot of different macros there. The brown one is sargassum, the green one appears to be caulerpa verticillata, and the red one appears to be a type of gracilaria.

I also see scinaia, halimeda, caulerpa prolifera, maybe dictyota, and others I can't ID from those pics. Nice mix

Thanks for the help identifying these. That confirms what I thought they were. The C. verticillata was the one that took the longest to sort out. They were all volunteers the rock I got and was very pleased to see the variety.
