I don't see the gray spots. Also not dragons breath btw, it's Gracilaria hayi

Whoops the second picture shouldnt be there, only the first picture.

I bought from one of Swedens biggest resellers. Would you say that the info in the link below is wrong?

Uhm yes? I suppose. Dragons breath is a species of Halymenia rather than Dictyota. The picture on the website is a species of Gracilaria, either G. tikvahiae or G. parvispora. But I don't blame them, algae IDs are hard

Hmm.. Would you say its a good absorber of nitrate?

Yes. Give it light and some decent flow to prevent hair algae from growing on it. Frag off a little bit every now and then and use it as fertilizer for your garden or something
