What cause this to my hammer ?

I have my hammer for 2-3 months, it look like this... This is the only coral looking poor like this in my 20g setup... Initially it was really healty.



Same lighting and placement (bottom) for this torch and look really happy...


Params:

Temp: 26Cį
PH: 8
Alk: 9 dKH (stable)
Ca: 450ppm (stable)
Mg: 1400 (Stable)
NO3: < 2 ppm
PO4: undetectable so <0.05ppm

It's on a low flow area. All my corals (mushs, zoas, FS, torch and duncan) look happy, but not this one

NOTE: I'm currently fighting dinoflagellates, but my coral look like this since before I saw the firsts dinos.

Plz help.

I just found 3 bristles worms, and a nudibranch last night, but I think they did come with a rock I bought there's 2 days. Not sure where they're coming from, but I really don't enjoy them !

Bought a trap for the bristles worms, and I don't know what to do with the nudi. I just found one, that I killed !

Bristle worms aren't going to have any interest in a healthy coral and there aren't any nudibranch I'm aware of that go after LPS...they are a soft/polyp only kinda feeder in terms of our worries about predators in home aquariums.
I'd suspect that the dinos, if you truly have dinos, is causing the issue...that or it is what they are feeding off of causing what is going on.

Yeah, for sure it's dinos, as the brown slime make bubbles and long "tentacles" with bubbles on it... Maybe it's cyanobacterias ?

It is possible the hammer dying is feeding the dinos ?

0 ppm PO4
2 ppm NO3

Probably NO3 dropped, as I started vodka dosing since 2 weeks to drop levels near 0. A guys will check my params again in 1 week, to see if my vodka dosing and water changes were usefull.

Thanks for the advice, if vodka dosing doesn't work for dinos (or maybe cyanos) I'll try 3 days blackout.

No, because it isn't rotting away. There is something else going on feeding the issue, either feeding too much, or not using ro/di water, not enough water changes...

For sure I don't feed too much, my clowns eat everything I give them in 1 minute.

I'm Using RODI, but maybe true on the waterchanges, last month I did 1x30% WC in the month.

In the last two weeks, I did 4x25% WC to bring NO3 down. (Params remained stables).

So maybe dinos will get rid by themselves by keeping on waterchanges ? I hope

Low to low-medium. I heard they don't like too much flow.

Have you tried moving him? Has there been any changes in the tank at all?
