Wall hammer death

[mathvmendes]

Hi there! I normally would search before posting, but this time I feel like I need a more "exclusive" answer for my problem.
Im not new to saltwater, but im definitely inexperienced. My tank is 4mo, 150Liters, with softs and LPS for now.

So, I just arrived home after work (I work 24 or 36 hours straight, away from home, on the weekends) and saw my wall hammer, otherwise healthy, basically dead, with a brown slime covering half of it, and the other half kinda melted. First thing on my mind was bjd. What is strange to me, is that it went from healthy, or at least with no signs of desease, to dead in 2 days.
Then i started searching for other desasters, because why stop with only one right?

Well, found one chalice and one favia with some tissue receding, nothing major, but enough to make me very worried.


Problems that im dealing with recently:
- elegance closed, with a white web envolving it (started after a dipped it last week, because of 1 flatworm i found)
-tissue receding on my hammers and frogspawns, maybe because of too much flow?
So i changed my wavemakers. Bought a gyre pump with controller last week, and fixed the issue (or maybe not? Still see some tissue receding, but also some regrowing, idk how this works, first time dealing with it)

Also, 3 days ago i added a dosing pump, only for Kh for now, since Ca and Mg are pretty stable.
Because of that dosing pump, i thought the alk could be really high, idk, so i tested.

Parameters: kh 8.4 (was 7.6 before starting the dosing, 3 days ago), Ca 430, Mg 1410, nitrate 3, phos 0.15, ph 8.2.
Salinity 1.025, temp between 25,5C and 26C.
I test every week, and apart from the kh, the others have been this way for like 3-4 weeks.

I do weekly 20%WC as well, with aquaforest salt and RODI water.

Im surely forgetting some information, but thats it. Sorry for this book disguised as post lol

And the question is: what is happening?

Thanks in advance!

Make sure you’ve removed the wall hammer from the tank and preferably performed a large water change. BJD spreads easily through lps coral. Wall hammers have a very bad survival rate. It seems like they are very susceptible to disease and since all polyps are connected it kills the whole coral. Branching hammers can usually be saved by cutting off the affected heads.

There has been some experimenting with cipro for BJD if you search the site. Pics of the recession might help. If it’s minor, just keep an eye on it. If it’s more extreme you may want to separate and potentially treat them with cipro.

Thanks for the reply!

Did a 50-60%WC yesterday, and forgot to mention that i removed the hammer the moment i saw brown slime in it.

Yesterday i removed the hammers, torch and frog and dipped then with iodine. Today some look better, but i dont really have the experience to say if its real or just my imagination, and i dont want to worsen things up by overmanipulating the corals

Took some pictures with lights off, so everything is closed. During the day they are actually really opened, like most healthy ones i see on internet. The torch started to puff the flesh band around the skeleton, idk if its a good sign. But the recession is getting worse on the frog i guess.

Honestly, im really lost. Parameters look good, no fish picking the corals, since i have only one shy firefish. No pests, light is on 60% since ever.
Only changes were a maxspect gyre 2k, that is running on 20% random, and the bubble magus dosing pump. Maybe the kh product was contaminated by some plastic? Used a atoxic polypropylene container

What am i missing?
