Algae ID

[Andrei P]

Hello ,
what algae do you think this is ? Dino ? I have 2 more SPS with this brown jelly thing on them and that is all . Nothing on the sand / rocks .
I have 0 No3 ( Salifert) and 0.01 PO4 ( Hanna ). This thing with super low nutrient is something new in my tank , something that I don't want, but somehow it happened after I went with Tropic Marin Bio Actif Salt.

PS: At the moment I'm dealing with bryopsis and I'm on day 8 with Fluconazole . This brown thing was on 1 of my corals a week before I start this treatment.

For the moment I've stopped the light on my chaeto and took out the RowaPhos. On day 14 of the treatment I will add carbon and do a WC . The WC may be a bad idea with this salt but ... IDK .

The tank has 2 years


Thanks

With them type of nutrient levels I suspect it might be dinos, when I had a spell of dinos in the past it seemed to be on the sandbed or hanging onto corals as yours is.

You've stopped rowa and chaeto so hopefully your nutrients levels will elevate a bit
