Brown algae ID please . . .

Looks like it will be a very nice setup.

The first photo is sargassum.

The one other photo that you call a sponge or algae must be what I thought was dictyota. From a distance it has a very similar appearance.


Good luck with the new setup!
 
I'm not sure if you ever resolved you algae questions, but this is my guess.
